Description Paul Webster

I was working the Debug perspective, selected a breakpoint, and checked the conditional checkbox to start editing the condition.  I got the following NPE.

It doesn't appear to prevent the conditions from being saved.

eclipse.buildId=M20130125-1200
java.version=1.7.0_11
java.vendor=Oracle Corporation
BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=en_US
Command-line arguments:  -os linux -ws gtk -arch x86_64 -data /opt/pwebster/workspaces/build42x/

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
