Hello Rory, Just in time ! We announced the JDK9 full compatibility less than 2 days ago: https://josm.openstreetmap.de/ticket/11924
The compatibility effort was significant, but shared with the whole Java ecosystem (as we created bug reports to Ant, Groovy, EqualsVerifier, Geotools, FindBugs/SpotBugs, ErrorProne, etc.). Aside Jigsaw, the three JDK9 changes that impacted us most were: 1) The Math improvements to Math.cos in b105 (JDK-8143353, see https://josm.openstreetmap.de/ticket/11889 + https://josm.openstreetmap.de/ticket/13387). It took us a long time to spot why our floating point calculations changed in JDK9. But we noticed a huge performance gain, and more accurate results too. This is a huge improvement, thanks! 2) The deprecation of _MASK constants in favor of _DOWN_MASK constants (JDK-8143077). It was not easy to switch because ActionEvent does not provide extended modifiers (there's no getModifiersEx() method in this class. I think it should have been added in 9, could you please consider it in 10 ?). 3) The impossibility to disable the "proprietary API warning" in 9 (we disabled it with non-supported option -XDignore.symbol.file in 8). Until we switch our codebase to a version of Java providing the new certificate creation API (JDK-8058778), we must keep our current implementation based on sun.x509 packages. Currently the best I can do is tell our Jenkins instance to filter this warning. Congrats for this major release of Java, Best regards, Vincent 2017-08-08 11:30 GMT+02:00 Rory O'Donnell <[email protected]>: > > Hi Vincent, > > Thank you very much for all your testing of JDK 9 during its development! > Such contributions have significantly helped shape and improve JDK 9. > > Now that we have reached the JDK 9 Final Release Candidate phase [1] , I > would like to ask if your project can be considered to be 'ready for JDK > 9', or if there are any remaining show stopper issues which you've > encountered when testing with the JDK 9 release candidate. > > JDK 9 b181 is available at http://jdk.java.net/9/ > > If you have a public web page, mailing list post, or even a tweet > announcing you project's readiness for JDK 9, I'd love to add the URL to > the upcoming JDK 9 readiness page on the Quality Outreach wiki. > > > Looking forward to hearing from you, > Rory > > [1] http://openjdk.java.net/projects/jdk9/ > > -- > Rgds,Rory O'Donnell > Quality Engineering Manager > Oracle EMEA , Dublin, Ireland > >
