Hi Andrew,
I just tried Forte for Java 3.0 Early Access, and it shows the above
problem quite easily during startup. I ran it with truss(1), and the
last part of the output is:

Remember, this is only with java -hotspot; java -classic works fine.
Surprisingly the previous Forte for Java (2.0) works fine both with
-hotspot and -classic.
You can download the 3.0 Early Access version from
http://eap.netbeans.com after registering (free).
