Hmm.  I just tried this again, and it does work with anything printed by
System.out.println or System.err.println, but it doesn't seem to get the
exception information.

I think that might be a limitation of RPG.  When the RPG runtime makes
your method call, it checks for a JNI exception, and if one occurred, it
sends the RNX0301 message.  The RPG runtime -could- (but doesn't
currently) call a JNI function called ExceptionDescribe that would
output the exception information to stderr.  And since the RPG runtime
then handles the JNI exception, it's not possible for the RPG program to
later call ExceptionDescribe itself.

It might be possible in the future to have an environment variable that
would tell the RPG runtime to call ExceptionDescribe for exceptions on
method calls.
