Hi Josef, first of all, the right mailing list for your question would be porters-...@openjdk.java.net (I've redirected this mail to the new list )
Porting to OpenVMS Itanium would be particularly hard, because it involves two steps: 1. porting to a new processor architecture (IA64) 2. porting to a new operating system For the first step (the Itanium port) you could try to Zero port which is part of the OpenJDK 7 (http://openjdk.java.net/projects/zero/, http://icedtea.classpath.org/wiki/ZeroSharkFaq). But you should be aware of the following facts: - as far as I know, Zero is currently unmaintained so it may be already difficult to even compile/build it - Zero is an "interpreter only" port so the performance may be not what you expect After you got the Zero port running on Linux/IA64 you could start with the OS port to OpenVMS. And bear in mind, creating a production-ready OpenJDK port to a new architecture/platform is a multi man-year project which requires deep assembler and system programming knowledge.
