Description Jiri Sedlacek 2014-01-07 14:42:17 UTC 
Steps (the same as for Bug 240063, might be related)

  1/ Win7 64b, 7u45 64b, Anagram Game
  2/ Custom CPU, advanced, all advanced settings selected
  3/ Start profiling, NPE shows immediately after displaying Locks window

In the corresponding bugdb, these exceptions are thrown:

  java.lang.NullPointerException at org.netbeans.lib.profiler.results.cpu.CPUCallGraphBuilder.markerMethodEntry (CPUCallGraphBuilder.java:1143)
  java.lang.NullPointerException at org.netbeans.lib.profiler.results.cpu.CPUCallGraphBuilder.plainMethodEntry (CPUCallGraphBuilder.java:1222)

See the bugdb for more details.

Another bugdb report, happens also for Methods/Sampling.

summary:     bugfix #240084, initialize hasMonitorInfo using isLockContentionMonitoringEnabled() - NEW_MONITOR event can arrive after METHOD_ENTRY_MONITOR (due to thread-local data buffers) and in such case hasMonitorInfo is set incorrectly when METHOD_ENTRY_MONITOR is processed

Sampling case is different issue.
Comment 3 Quality Engineering 2015-03-20 03:25:55 UTC 
Integrated into 'main-silver', will be available in build *201503200001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
