Most of the Checker Framework is licensed under the GNU General Public
|
||
|
License, version 2 (GPL2), with the classpath exception. The text of this
|
||
|
license appears below. This is the same license used for OpenJDK.
|
||
|
|
||
|
A few parts of the Checker Framework have more permissive licenses.
|
||
|
|
||
|
* The annotations are licensed under the MIT License. (The text of this
|
||
|
license appears below.) More specifically, all the parts of the Checker
|
||
|
Framework that you might want to include with your own program use the
|
||
|
MIT License. This is the checker-qual.jar file and all the files that
|
||
|
appear in it: every file in a qual/ directory, plus utility files such
|
||
|
as NullnessUtil.java, RegexUtil.java, SignednessUtil.java, etc.
|
||
|
In addition, the cleanroom implementations of third-party annotations,
|
||
|
which the Checker Framework recognizes as aliases for its own
|
||
|
annotations, are licensed under the MIT License.
|
||
|
|
||
|
Some external libraries that are included with the Checker Framework have
|
||
|
different licenses.
|
||
|
|
||
|
* javaparser is dual licensed under the LGPL or the Apache license -- you
|
||
|
may use it under whichever one you want. (The javaparser source code
|
||
|
contains a file with the text of the GPL, but it is not clear why, since
|
||
|
javaparser does not use the GPL.) See file stubparser/LICENSE
|

|
and the source code of all its files.
|

Version 2, June 1991

59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
||
|
|
||
|
Everyone is permitted to copy and distribute verbatim copies of this license
|
||
|
document, but changing it is not allowed.
|
||
|
|
||
|
Preamble
|
||
|
|
||
|
The licenses for most software are designed to take away your freedom to share
|
||
|
and change it. By contrast, the GNU General Public License is intended to
|
||
|
guarantee your freedom to share and change free software--to make sure the
|
||
|
software is free for all its users. This General Public License applies to
|
||
|
most of the Free Software Foundation's software and to any other program whose
|
||
|
authors commit to using it. (Some other Free Software Foundation software is
|
||
|
covered by the GNU Library General Public License instead.) You can apply it to
|
||
|
your programs, too.
|
||
|
|
||
|
When we speak of free software, we are referring to freedom, not price. Our
|
||
|
General Public Licenses are designed to make sure that you have the freedom to
|
||
|
distribute copies of free software (and charge for this service if you wish),
|
||
|
that you receive source code or can get it if you want it, that you can change
|
||
|
the software or use pieces of it in new free programs; and that you know you
|
||
|
can do these things.
|
||
|
|
||
|
To protect your rights, we need to make restrictions that forbid anyone to deny
|
||
|
you these rights or to ask you to surrender the rights. These restrictions
|
||
|
translate to certain responsibilities for you if you distribute copies of the
|
||
|
software, or if you modify it.
|
||
|
|
||
|
For example, if you distribute copies of such a program, whether gratis or for
|
||
|
a fee, you must give the recipients all the rights that you have. You must
|
||
|
make sure that they, too, receive or can get the source code. And you must
|
||
|
show them these terms so they know their rights.
|
||
|
|
||
|
We protect your rights with two steps: (1) copyright the software, and (2)
|
||
|
offer you this license which gives you legal permission to copy, distribute
|
||
|
and/or modify the software.
|
||
|
|
||
|
Also, for each author's protection and ours, we want to make certain that
|
||
|
everyone understands that there is no warranty for this free software. If the
|
||
|
software is modified by someone else and passed on, we want its recipients to
|
||
|
know that what they have is not the original, so that any problems introduced
|
||
|
by others will not reflect on the original authors' reputations.
|
||
|
|
||
|
Finally, any free program is threatened constantly by software patents. We
|
||
|
wish to avoid the danger that redistributors of a free program will
|
||
|
individually obtain patent licenses, in effect making the program proprietary.
|
||
|
To prevent this, we have made it clear that any patent must be licensed for
|
||
|
everyone's free use or not licensed at all.
|
||
|
|
||
|
The precise terms and conditions for copying, distribution and modification
|
||
|
follow.
|
||
|
|
||
|
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||
|
|
||
|
0. This License applies to any program or other work which contains a notice
|
||
|
placed by the copyright holder saying it may be distributed under the terms of
|
||
|
this General Public License. The "Program", below, refers to any such program
|
||
|
or work, and a "work based on the Program" means either the Program or any
|
||
|
derivative work under copyright law: that is to say, a work containing the
|
||
|
Program or a portion of it, either verbatim or with modifications and/or
|
||
|
translated into another language. (Hereinafter, translation is included
|
||
|
without limitation in the term "modification".) Each licensee is addressed as
|
||
|
"you".
|
||
|
|
||
|
Activities other than copying, distribution and modification are not covered by
|
||
|
this License; they are outside its scope. The act of running the Program is
|
||
|
not restricted, and the output from the Program is covered only if its contents
|
||
|
constitute a work based on the Program (independent of having been made by
|
||
|
running the Program). Whether that is true depends on what the Program does.
|
||
|
|
||
|
1. You may copy and distribute verbatim copies of the Program's source code as
|
||
|
you receive it, in any medium, provided that you conspicuously and
|
||
|
appropriately publish on each copy an appropriate copyright notice and
|
||
|
disclaimer of warranty; keep intact all the notices that refer to this License
|
||
|
and to the absence of any warranty; and give any other recipients of the
|
||
|
Program a copy of this License along with the Program.
|
||
|
|
||
|
You may charge a fee for the physical act of transferring a copy, and you may
|
||
|
at your option offer warranty protection in exchange for a fee.
|
||
|
|
||
|
2. You may modify your copy or copies of the Program or any portion of it, thus
|
||
|
forming a work based on the Program, and copy and distribute such modifications
|
||
|
or work under the terms of Section 1 above, provided that you also meet all of
|
||
|
these conditions:
|
||
|
|
||
|
a) You must cause the modified files to carry prominent notices stating
|
||
|
that you changed the files and the date of any change.
|
||
|
|
||
|
b) You must cause any work that you distribute or publish, that in whole or
|
||
|
in part contains or is derived from the Program or any part thereof, to be
|
||
|
licensed as a whole at no charge to all third parties under the terms of
|
||
|
this License.
|
||
|
|
||
|
c) If the modified program normally reads commands interactively when run,
|
||
|
you must cause it, when started running for such interactive use in the
|
||
|
most ordinary way, to print or display an announcement including an
|
||
|
appropriate copyright notice and a notice that there is no warranty (or
|
||
|
else, saying that you provide a warranty) and that users may redistribute
|
||
|
the program under these conditions, and telling the user how to view a copy
|
||
|
of this License. (Exception: if the Program itself is interactive but does
|
||
|
not normally print such an announcement, your work based on the Program is
|
||
|
not required to print an announcement.)
|
||
|
|
||
|
These requirements apply to the modified work as a whole. If identifiable
|
||
|
sections of that work are not derived from the Program, and can be reasonably
|
||
|
considered independent and separate works in themselves, then this License, and
|
||
|
its terms, do not apply to those sections when you distribute them as separate
|
||
|
works. But when you distribute the same sections as part of a whole which is a
|
||
|
work based on the Program, the distribution of the whole must be on the terms
|
||
|
of this License, whose permissions for other licensees extend to the entire
|
||
|
whole, and thus to each and every part regardless of who wrote it.
|
||
|
|
||
|
Thus, it is not the intent of this section to claim rights or contest your
|
||
|
rights to work written entirely by you; rather, the intent is to exercise the
|
||
|
right to control the distribution of derivative or collective works based on
|
||
|
the Program.
|
||
|
|
||
|
In addition, mere aggregation of another work not based on the Program with the
|
||
|
Program (or with a work based on the Program) on a volume of a storage or
|
||
|
distribution medium does not bring the other work under the scope of this
|
||
|
License.
|
||
|
|
||
|
3. You may copy and distribute the Program (or a work based on it, under
|
||
|
Section 2) in object code or executable form under the terms of Sections 1 and
|
||
|
2 above provided that you also do one of the following:
|
||
|
|
||
|
a) Accompany it with the complete corresponding machine-readable source
|
||
|
code, which must be distributed under the terms of Sections 1 and 2 above
|
||
|
on a medium customarily used for software interchange; or,
|
||
|
|
||
|
b) Accompany it with a written offer, valid for at least three years, to
|
||
|
give any third party, for a charge no more than your cost of physically
|
||
|
performing source distribution, a complete machine-readable copy of the
|
||
|
corresponding source code, to be distributed under the terms of Sections 1
|
||
|
and 2 above on a medium customarily used for software interchange; or,
|
||
|
|
||
|
c) Accompany it with the information you received as to the offer to
|
||
|
distribute corresponding source code. (This alternative is allowed only
|
||
|
for noncommercial distribution and only if you received the program in
|
||
|
object code or executable form with such an offer, in accord with
|
||
|
Subsection b above.)
|
||
|
|
||
|
The source code for a work means the preferred form of the work for making
|
||
|
modifications to it. For an executable work, complete source code means all
|
||
|
the source code for all modules it contains, plus any associated interface
|
||
|
definition files, plus the scripts used to control compilation and installation
|
||
|
of the executable. However, as a special exception, the source code
|
||
|
distributed need not include anything that is normally distributed (in either
|
||
|
source or binary form) with the major components (compiler, kernel, and so on)
|
||
|
of the operating system on which the executable runs, unless that component
|
||
|
itself accompanies the executable.
|
||
|
|
||
|
If distribution of executable or object code is made by offering access to copy
|
||
|
from a designated place, then offering equivalent access to copy the source
|
||
|
code from the same place counts as distribution of the source code, even though
|
||
|
third parties are not compelled to copy the source along with the object code.
|
||
|
|
||
|
4. You may not copy, modify, sublicense, or distribute the Program except as
|
||
|
expressly provided under this License. Any attempt otherwise to copy, modify,
|
||
|
sublicense or distribute the Program is void, and will automatically terminate
|
||
|
your rights under this License. However, parties who have received copies, or
|
||
|
rights, from you under this License will not have their licenses terminated so
|
||
|
long as such parties remain in full compliance.
|
||
|
|
||
|
5. You are not required to accept this License, since you have not signed it.
|
||
|
However, nothing else grants you permission to modify or distribute the Program
|
||
|
or its derivative works. These actions are prohibited by law if you do not
|
||
|
accept this License. Therefore, by modifying or distributing the Program (or
|
||
|
any work based on the Program), you indicate your acceptance of this License to
|
||
|
do so, and all its terms and conditions for copying, distributing or modifying
|
||
|
the Program or works based on it.
|
||
|
|
||
|
6. Each time you redistribute the Program (or any work based on the Program),
|
||
|
the recipient automatically receives a license from the original licensor to
|
||
|
copy, distribute or modify the Program subject to these terms and conditions.
|
||
|
You may not impose any further restrictions on the recipients' exercise of the
|
||
|
rights granted herein. You are not responsible for enforcing compliance by
|
||
|
third parties to this License.
|
||
|
|
||
|
7. If, as a consequence of a court judgment or allegation of patent
|
||
|
infringement or for any other reason (not limited to patent issues), conditions
|
||
|
are imposed on you (whether by court order, agreement or otherwise) that
|
||
|
contradict the conditions of this License, they do not excuse you from the
|
||
|
conditions of this License. If you cannot distribute so as to satisfy
|
||
|
simultaneously your obligations under this License and any other pertinent
|
||
|
obligations, then as a consequence you may not distribute the Program at all.
|
||
|
For example, if a patent license would not permit royalty-free redistribution
|
||
|
of the Program by all those who receive copies directly or indirectly through
|
||
|
you, then the only way you could satisfy both it and this License would be to
|
||
|
refrain entirely from distribution of the Program.
|
||
|
|
||
|
If any portion of this section is held invalid or unenforceable under any
|
||
|
particular circumstance, the balance of the section is intended to apply and
|
||
|
the section as a whole is intended to apply in other circumstances.
|
||
|
|
||
|
It is not the purpose of this section to induce you to infringe any patents or
|
||
|
other property right claims or to contest validity of any such claims; this
|
||
|
section has the sole purpose of protecting the integrity of the free software
|
||
|
distribution system, which is implemented by public license practices. Many
|
||
|
people have made generous contributions to the wide range of software
|
||
|
distributed through that system in reliance on consistent application of that
|
||
|
system; it is up to the author/donor to decide if he or she is willing to
|
||
|
distribute software through any other system and a licensee cannot impose that
|
||
|
choice.
|
||
|
|
||
|
This section is intended to make thoroughly clear what is believed to be a
|
||
|
consequence of the rest of this License.
|
||
|
|
||
|
8. If the distribution and/or use of the Program is restricted in certain
|
||
|
countries either by patents or by copyrighted interfaces, the original
|
||
|
copyright holder who places the Program under this License may add an explicit
|
||
|
geographical distribution limitation excluding those countries, so that
|
||
|
distribution is permitted only in or among countries not thus excluded. In
|
||
|
such case, this License incorporates the limitation as if written in the body
|
||
|
of this License.
|
||
|
|
||
|
9. The Free Software Foundation may publish revised and/or new versions of the
|
||
|
General Public License from time to time. Such new versions will be similar in
|
||
|
spirit to the present version, but may differ in detail to address new problems
|
||
|
or concerns.
|
||
|
|
||
|
Each version is given a distinguishing version number. If the Program
|
||
|
specifies a version number of this License which applies to it and "any later
|
||
|
version", you have the option of following the terms and conditions either of
|
||
|
that version or of any later version published by the Free Software Foundation.
|
||
|
If the Program does not specify a version number of this License, you may
|
||
|
choose any version ever published by the Free Software Foundation.
|
||
|
|
||
|
10. If you wish to incorporate parts of the Program into other free programs
|
||
|
whose distribution conditions are different, write to the author to ask for
|
||
|
permission. For software which is copyrighted by the Free Software Foundation,
|
||
|
write to the Free Software Foundation; we sometimes make exceptions for this.
|
||
|
Our decision will be guided by the two goals of preserving the free status of
|
||
|
all derivatives of our free software and of promoting the sharing and reuse of
|
||
|
software generally.
|
||
|
|
||
|
NO WARRANTY
|
||
|
|
||
|
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
|
||
|
THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
|
||
|
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE
|
||
|
PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
|
||
|
INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
|
||
|
FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
|
||
|
PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE,
|
||
|
YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||
|
|
||
|
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
|
||
|
ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE
|
||
|
PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
||
|
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
|
||
|
INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
|
||
|
BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
|
||
|
FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER
|
||
|
OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
|
||
|
|
||
|
END OF TERMS AND CONDITIONS
|
||
|
|
||
|
How to Apply These Terms to Your New Programs
|
||
|
|
||
|
If you develop a new program, and you want it to be of the greatest possible
|
||
|
use to the public, the best way to achieve this is to make it free software
|
||
|
which everyone can redistribute and change under these terms.
|
||
|
|
||
|
To do so, attach the following notices to the program. It is safest to attach
|
||
|
them to the start of each source file to most effectively convey the exclusion
|
||
|
of warranty; and each file should have at least the "copyright" line and a
|
||
|
pointer to where the full notice is found.
|
||
|
|
||
|
One line to give the program's name and a brief idea of what it does.
|
||
|
|
||
|
Copyright (C) <year> <name of author>

This program is free software; you can redistribute it and/or modify it
|
||
|
under the terms of the GNU General Public License as published by the Free

This program is distributed in the hope that it will be useful, but WITHOUT
|

ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or
|
||

FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for
|

|
more details.
|
||
|
|
||
|
You should have received a copy of the GNU General Public License along
|
||
|
with this program; if not, write to the Free Software Foundation, Inc., 59

||
|
Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
||
|
|
||
|
Also add information on how to contact you by electronic and paper mail.
|
||
|
|
||
|
If the program is interactive, make it output a short notice like this when it
|
||
|
starts in an interactive mode:
|
||
|
|
||
|
Gnomovision version 69, Copyright (C) year name of author Gnomovision comes
|
||
|
with ABSOLUTELY NO WARRANTY; for details type 'show w'. This is free
|
||
|
software, and you are welcome to redistribute it under certain conditions;
|
||
|
type 'show c' for details.
|
||
|
|
||
|
The hypothetical commands 'show w' and 'show c' should show the appropriate
|
||
|
parts of the General Public License. Of course, the commands you use may be
|
||
|
called something other than 'show w' and 'show c'; they could even be
|
||
|
mouse-clicks or menu items--whatever suits your program.
|
||
|
|
||
|
You should also get your employer (if you work as a programmer) or your school,
|
||
|
if any, to sign a "copyright disclaimer" for the program, if necessary. Here
|
||
|
is a sample; alter the names:
|
||
|
|

|
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|

'Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
|
||
|
proprietary programs. If your program is a subroutine library, you may
|
||
|
consider it more useful to permit linking proprietary applications with the
|
||
|
library. If this is what you want to do, use the GNU Library General Public
|
||
|
License instead of this License.
|

|
|

|
||
|
"CLASSPATH" EXCEPTION TO THE GPL
|
||
|
|
||
|
Certain source files distributed by Oracle America and/or its affiliates are
|
||
|
subject to the following clarification and special exception to the GPL, but
|
||
|
only where Oracle has expressly included in the particular source file's header
|
||
|
the words "Oracle designates this particular file as subject to the "Classpath"
|
||
|
exception as provided by Oracle in the LICENSE file that accompanied this code."
|
||
|
|
||
|
Linking this library statically or dynamically with other modules is making
|
||
|
a combined work based on this library. Thus, the terms and conditions of
|
||
|
the GNU General Public License cover the whole combination.
|
||
|
|
||
|
As a special exception, the copyright holders of this library give you
|
||
|
permission to link this library with independent modules to produce an
|
||
|
executable, regardless of the license terms of these independent modules,
|
||
|
and to copy and distribute the resulting executable under terms of your
|
||
|
choice, provided that you also meet, for each linked independent module,
|
||
|
the terms and conditions of the license of that module. An independent
|
||
|
module is a module which is not derived from or based on this library. If
|
||
|
