Yes. However, the gcj runtime needs a certain amount of
initialization. You can't just start making Java calls -- you'll get
crashes, as you saw. Read about the CNI Invocation API in the gcj
docs. (This is in the 3.3 docs anyway; probably not in 3.2.)
A simpler thing to do is to make `main' be a Java method.
Then when you link with `--main=...', the initialization will happen
for you.

Indeed.
