Simon, the name of the native method is correct.  At runtime this
name is usually translated so the java code can find the proper
JNI method.  On the windows platform this translation is not taking
place.  I reported it to the gcc team via an email about two
weeks ago.   I still haven't received a response.  I will post to the
list one more time and follow up with a bugzilla report.

The method call is correct.  If you run the java file through javah you will
see that this is the method created.
