Sun Microsystems Inc., the
inventor and leading advocate of Java(tm) technology, today announced
that it has posted its next version of Java(tm) 2 Platform Standard
Edition (J2SE(tm)) to the developer community for early review and
developer involvement. J2SE 6 is code-named “Project Mustang”. Available as part of a new project launched this week on, this marks the first time Sun has made source and
binary code bundles for a J2SE release available while it is still under
active development. This move will provide an unprecedented opportunity
for developers worldwide to participate in the innovation of the Java

“Last June we experimented with a transparent development process by
releasing snapshots of the J2SE 5.0 software early and it was a great
success,” said Jeff Jackson, vice president Java platform development
and Java tools. “Inspired by the enthusiasm we found in the Java
development community and their desire to participate earlier in the
process, we are taking it a few steps further by releasing source code,
under the simplified Java Research License, and an open community
project launched on”

Java developers can join the new Java platform project on to
download build 12 of the next version of J2SE source code and
participate in developer forums. In the future, is expected to
enable a streamlined process for patch submissions. Sun is working
through details on how these bug fixes and other non-JSR code from the
community will be managed.

As committed at the JavaOne(sm) conference in June of this year, Sun has
taken steps to simplify the Java technology license to give easier
access to non-profit and academic developers. Today Sun has implemented
this simplified license, known as the Java Research License (JRL).
Simpler than the previous Sun Community Source Licensing (SCSL) that has
been in force for Java technology for nearly six years, the JRL provides
developers and researchers with greater flexibility. Sun is also
considering adjustments to the Java distribution license to continue to
ease developer access.
