Early Access builds for JDK 9 b51 are available on java.net

Rory O'Donnell

Hi Joerg,

Early Access build for JDK 9 b51 available on java.net, summary of  changes are listed here

I'd also like to use this opportunity to point you to JEP 238: Multi-Version JAR Files [0],
which is currently a Candidate JEP for JDK 9.

It's goal is to extend the JAR file format to allow multiple, JDK release-specific versions of class
files to coexist in a single file. An additional goal is to backport the run-time changes to
JDK 8u60, thereby enabling JDK 8 to consume multi-version JARs. For a detailed discussion,
please see the corresponding thread on the core-libs-dev mailing list. [1]

Please keep in mind that a JEP in the Candidate state is merely an idea worthy of consideration
by JDK Release Projects and related efforts; there is no commitment that it will be delivered in
any particular release.

Comments, questions, and suggestions are welcome on the corelibs-dev mailing list. (If you
haven’t already subscribed to that list then please do so first, otherwise your message will be
discarded as spam.)
