No idea, how much the dependencies correspond with "would/wouldn't work". I wouldn't bet on that. The question, why would you so desperately try to have 1.5 JDK as (generation-1 without migration overlay) system vm? It can only break things, and gain you nothing. Somebody correct me if I'm wrong, but the bytecode compiled will be the same no matter which JDK you use. Any optimisations are done with run-time JIT compiling, and depends on the VM running the bytecode (which can be different from the VM used to compile). So, without migration overlay, you should best follow the java 1.5 faq, have 1.4 as sytem vm and use whatever vm as user vm. Caster -- gentoo-java@gentoo.org mailing list
