Hi Jason/Tomaz, JDK 9 Early Access with Project Jigsaw build b36 is available on java.net [1] The goal of Project Jigsaw [2] is to design and implement a standard module system for the Java SE Platform, and to apply that system to the Platform itself and to the JDK. As described in JEP 220 [3], this build provides a new runtime image structure. For example, this new runtime image does not install an rt.jar file or a tools.jar file. Please refer to Project Jigsaw's updated project pages [2] & [4] and Mark Reinhold's announcement email [5] for further details. We are very interested in your experiences testing this build. Comments, questions, and suggestions are welcome on the jigsaw-dev mailing list or else submit bug reports via bugs.java.com.
