Odd. Are you running GlassFish on JDK 5 or JDK 6? You'll get better
results if running on JDK 6 as VisualVM will use the profiler api's
available in that version. IIRC, what you describe is what will happen
if you are running on JDK 5.

I don't think this is necessarily true. But see above, re: JDK 5.
