It's not a general solution. For one thing, with JNI invocation programs
are free to startup (and bind to malloc, etc.) before loading the gcj
runtime.
I don't see how local refs are avoidable if JNI is going to work. There
are probably faster ways to handle them, though. (I'm not worried about
global refs, which are relatively uncommon.)
