Early Access builds for JDK 9 b53 and JDK 8u60 b05 are available on java.net

Hi Joerg,

Early Access build for JDK 9 b53 available on java.net, summary of  changes are listed here

Early Access build for JDK 8u60 b05 is 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.)
