The goal of this Project is to produce an open-source reference implementation of the Java SE 9 Platform, to be defined by a forthcoming JSR in the Java Community Process.


The JDK 9 repositories have been open for bug fixes and small enhancements for some time now. Features for the release will be proposed and tracked via the JEP Process, as amended by the JEP 2.0 proposal (which will shortly be folded into the main JEP process document).
