I haven't investigated this yet. The RTTI thing is just a warning, so I assume that higher layers don't know that it happened. It is strange that this is even attempted for a Java type, though, because Java doesn't emit C++ RTTI info at all. There are other problems Java too, I'm working on a separate patch to fix some crashes. Tom
