Java Platform, Standard Edition 9 Reference Implementations

The official Reference Implementation for Java SE 9 (JSR 379) is based solely upon open-source code available from the JDK 9 Project in the OpenJDK Community.

The binaries are available under two different licenses: The GNU General Public License version 2, with the Classpath Exception and the Oracle Binary Code License. For a given platform the binaries under different licenses are built from exactly the same source code and are functionally equivalent; the only real difference is the license itself. Which license you choose will depend upon your particular business and legal requirements.

These binaries are for reference use only!

These binaries are provided for use by implementers of the Java SE 9 Platform Specification and are for reference purposes only. This Reference Implementation have been approved through the Java Community Process. Production-ready binaries under the GPL are available from Oracle; and in most popular Linux distributions.

International use restrictions

Due to limited intellectual property protection and enforcement in certain countries, the JDK source code may only be distributed to an authorized list of countries. You will not be able to access the source code if you are downloading from a country that is not on this list. We are continuously reviewing this list for addition of other countries.
