Created attachment 114173 [details] Screenshot of locked debugger in AWT-EventQueue-0 method evaluation. Product Version: NetBeans IDE 7.1 (Build 201112071828) Java: 1.7.0_02; Java HotSpot(TM) Client VM 22.0-b10 System: Linux Mint 10 version 2.6.35-22-generic running on i386; UTF-8; cs_CZ (nb) User directory: /home/cesilko/.netbeans/7.1 Cache directory: /home/cesilko/.netbeans/7.1/var/cache Description: ============ I installed fresh NetBeans 7.1 and JDK 7 Update 2 bundle and tested that "Stop on uncaught exceptions" setting works. Then I opened MemoryView testing project, toggled breakpoint at line 101 in MemoryView.java class and started debugger. Unfortunately, debugging session never fully started showing that AWT-EventQueue-0 was evaluating method... I have generated full thread dump, heap dump and application snapshot. I tried to restart debugging session several times to no avail. Finally restart of the IDE helped resolve it. What I did: =========== 1. I launched NetBeans 7.1 on JDK 7 Update 2 with empty userdir. 2. I tried to verify that issue #190527 was fixed. 3. Then I opened MemoryView testing project. 4. I toggled breakpoint at line 101 by Ctrl+F8 and then started debugger by Ctrl+F5. 5. Debugger locked on evaluation of method in AWT-EventQueue-0 and UI didn't show up.
Created attachment 114174 [details] Full thread dump when MemoryView debug session was stuck on evaluation of AWT-EventQueue-0.
After 15 minutes happened again. I only followed the sanity test specification until after Visual Debugging test. Again, had to restart IDE to discipline Debugger. :( -> Valid P2 IMO.
This is a duplicate of issue #206384. The thread dump and symptom is very similar. *** This bug has been marked as a duplicate of bug 206384 ***
