Description marco_bresciani 2012-01-30 13:46:47 UTC

This bug was originally marked as duplicate of bug 186297, that is already resolved. This bug is still valid, so this seems to be another bug, but it might be related.

Build: NetBeans IDE 7.0.1 (Build 201109201739)
VM: Java HotSpot(TM) Client VM, 20.5-b03, Java(TM) SE Runtime Environment, 1.6.0_30-b12
OS: Windows XP

User Comments:
kirkstork: Debugging java code.  Had recently added the "ToString" column to the variable window.  Crash occurred after stopping the debugger.

GUEST: Wanted to save a Java file

mmirilovic: - run one debugging session
- run another one (another project)
- open Loaded CLasses
- switch project in Debugging View
-> exception rises
... reproducible for 100%

GUEST: debugging a python file

alberto_deluca: Right-clicking project name to manually compile.

GUEST: nuffin
