The Checker Framework
Copyright 2004-present by the Checker Framework developers


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.

 * JUnit is licensed under the Common Public License v1.0 (see
   http://www.junit.org/license), with parts (Hamcrest) licensed under the
   BSD License (see http://hamcrest.org/JavaHamcrest/).

 * Libraries in plume-lib (https://github.com/plume-lib/) are licensed
   under the MIT License.

The Checker Framework includes annotations for the JDK in directory
checker/jdk/, and for some other libraries.  Each annotated library uses
the same license as the unannotated version of the library.
