This cannot work. ocaml-java is running in a JVM, but lablgtk2 is
written for the standard runtime, and assumes standard conventions for
the C bindings it needs.

What you could try to do is to use the standard runtime, and load the
JVM dynamically for running the Java library, and connect both via JNI.
There is a generator for such cross calls by Xavier:

I've never used it, though.
