Histograms in jVisualVM-VisualGC plugin "not supported"

[Michael Finocchiaro]

Perhaps the wrong forum for this question - if so please redirect me.
I upgraded my Java to Java7 but with the same parameters for starting my
Tomcat, I am no longer able to see the histograms in the VisualGC plugin to
jVisualVM that were so useful for checking the tuning of SurvivorRatio back
when I ran on Java6. Is this a known limitation on Java7 or did I miss a
command-line parameter somewhere?
Cheers,
Fino
