jvisualvm: java.lang.OutOfMemoryError: PermGen space

I get OOM while profiling a JMV.
If you do
jvisualvm -J-XX:MaxPermSize=512m
you get this:

ps -ef | grep visual

If your VisualVM hangs on "computing description", just restart the monitored JVMs (see http://stackoverflow.com/questions/6222210/visualvm-hanging-on-startup-computing-description )
Unfortunately, VisualVM has a limit of 64K profiled methods. There are options to limit to a subset of methods though...
