Description Jiri Skrivanek 2015-04-03 11:17:44 UTC 
In some circumstances searching in locks view never ends and blocks AWT. To reproduce:

- create sample Anagram project
- right-click project node and choose Profile
- select "Profile Multiple Features"
- select Telemetry, Threads and Locks
- click Profile and wait for profiler to start
- switch to Locks view
- Ctrl+F to open find entry point
- type e.g. awt and click Next several times. It blocks but not every time. AWT is running but never finishes. Stack traces are like these

BTW, I jump into this issue also when searching in CPU snapshot.
Comment 2 Jiri Sedlacek 2015-04-17 14:35:09 UTC 
Looks like searching for a string not present in a treetable data view cycles in an endless loop.

Fixed by http://hg.netbeans.org/profiler-main/rev/0ac89ff6a5b7.
