I came across CDS before when trying to get desktop java applications to start up faster. I also had hoped it would allow e.g. a constantly running fat server to run eclipse for multiple users more efficiently than each desktop duplicating work. http://lukas.zapletalovi.com/2012/11/want-faster-java-startups-in-fedora.html http://lukas.zapletalovi.com/2012/11/want-faster-java-startu... I had thought CDS was just for Sun and IBM implementations, but from the above I can infer it works on OpenJDK too. When you say, 'running many many java copies', do you mean java.exe?
