Hi Florian,
Early Access build for JDK 8u60 b18 <http://jdk8.java.net/download.html> is available on java.net, summary of changes are listed here. <http://www.java.net/download/jdk8u60/changes/jdk8u60-b18.html> As we enter the later phases of development for JDK 8u60, please log any show stoppers as soon as possible.
Early Access build for JDK 9 b66 <https://jdk9.java.net/download/> is available on java.net, summary of changes are listed here <http://www.java.net/download/jdk9/changes/jdk9-b66.html>.
The JDK 9 schedule of record is available on the JDK 9 Project page: http://openjdk.java.net/projects/jdk9
At https://wiki.openjdk.java.net/display/Adoption/JDK+9+Outreach you can find a (preliminary) list of other changes that might affect your project's code in JDK 9, and other things to consider when testing with JDK 9. I'd be curious to know if there is anything on that list you'd consider to have an effect on your project.
Please keep in mind that as JEPs and others changes are integrated into (or out of) JDK 9, the list will change
over time. Rgds,Rory -- Rgds,Rory O'Donnell Quality Engineering Manager Oracle EMEA , Dublin, Ireland
