Comment 2 Jiri Sedlacek 2012-12-03 16:50:29 UTC 
Confirmed it's a bug, org.netbeans.lib.profiler.server.Monitors.getMonitoredNumbers() computes wrong nTotalThreads, nSystemThreads and nUserThreads and the chart incorrectly displays nSystemThreads + nUserThreads (computed in org.netbeans.lib.profiler.results.monitor.VMTelemetryDataManager.addValuesInternal()).

summary:     bugfix #121381, set nSystemThreads to 0 if the number of system threads is not known; use ThreadInfo.getLiveServerThreads() to find out number of profiler (server) internal threads

Integrated into 'main-golden', will be available in build *201212070001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
