Hi Jason/Tomaz, JDK 9 with Project Jigsaw Early Access build b83 is available for download at jdk9.java.net/jigsaw <http://jdk9.java.net/jigsaw>;. Notable changes: * The -Xoverride option has been extended and renamed to -Xpatch, and the -XaddReads option has been restored [1] (changesets 04dd0430530e, 095fc622bf01). * ClassLoader::getPackage now works as it did previously, walking the class-loader hierarchy in order to find Package objects, which enables NetBeans to start up [2] (5805781b9370). * Class::getResource will now return a URL to a resource in a module, when invoked from code within that module (0fbe4c72638a). * The big module-summary table has been improved, and will now be posted with each build [3] (e922b207c170).
