Setting VisualVM Up

Does anyone have any experience getting this to work in order to profile a robot? I can get it to profile robocode but as soon as I try to profile my robot I get all sorts of errors in my robot's log output followed by it being "banned" by robocode.

Or are people using something else to do profiling? If so, what and how?

Thanks!

I do it with a special profiler class in my EvBotNG which is the part of my framelib. You can see the profiler class at profiler.java. The examples of it use are sprinkled all over EvBotNG. In the essence, when you need to start a timer for some code you say profiler.start( "methodName" ) and then at the end of the profiled code you say profiler.stop( "methodName" ). Once you ready to see the stats, you call profiler.formatAll( ). I do it at the end of every round.

This will print a nice looking statistic table which shows nested profiled chunks in a tree like structure. Something like

Well, you can try to disable security check of robocode. -Ddebug iirc
