Project Licenses

JDK source code is available under two different licenses in the OpenJDK Community.

1. GPL v2 open source license
2. Sun's Java Research License

Currently only the following components of the JDK are available under the GPL license:

* Java HotSpot virtual machine
* Java programming language compiler (javac)

The remainder of the JDK source will be released under GPL in the first half of 2007. Until this time, if you wish to experiment with or make contributions to the JDK, you must do so using source code under the JRL.

Other projects are also included in the OpenJDK community that do not include JDK source. These projects may use the JRL, GPL or other licenses.
