Description jtau8042 2012-07-18 14:44:41 UTC 
This bug was originally marked as duplicate of bug 212408, that is already resolved. This bug is still valid, so this seems to be another bug, but it might be related.

Build: NetBeans IDE Dev (Build 201207180002)
VM: Java HotSpot(TM) 64-Bit Server VM, 20.6-b01, Java(TM) SE Runtime Environment, 1.6.0_31-b05
OS: Linux

User Comments:
jtau8042: 1) start NetBeans
2) run Anagram game 
3) attach to it with Attach Profiler...
                   - use memory profiling, "Record object creation only"
                   - use local+dynamic attach
4) click Attach and wait until Live Results are available
5) click Modify Profiling Session and select "Record both object creation..."
6) click Attach, AssertionError occures

Comment 2 Jiri Sedlacek 2012-10-05 15:02:30 UTC 
Always reproducible. Steps:

 1/ Start the IDE
 2/ Start AnagramGame using the Run action
 3/ Dynamically attach to the AnagramGame, CPU sampling
 4/ Display Live results, get some data
 5/ Modify profiling to CPU instrumentation, default settings

AssertionError is thrown at NetBeansProfiler.java:123. Note this is in 7.3 Dev. A NPE is thrown in 7.2 at NetBeansProfiler.java:124, which is very likely a different symptom of the same bug.

Regression.
