Hi, I'm happy to announce that ZGC is now open source and that the source code is available in the project repository: http://hg.openjdk.java.net/zgc/zgc/ We've had some issues getting the project Web/Wiki in place, so in the meantime I've uploaded a temporary "Getting Started" document here: http://cr.openjdk.java.net/~pliden/zgc/ cheers, Per
