Description Darin Wright CLA 2008-02-28 12:38:32 EST 
With org.eclipse.debug.ui from HEAD as source in a workspace, I get a warning like:

"Potential null pointer access: The variable categories may be null at this location"

ContextualLaunchAction.java
org.eclipse.debug.ui/ui/org/eclipse/debug/ui/actions	line 248

Inspecting the code, the variable is assigned before this access, and I don't see how it could be null:

Reproduced.

Released inactive NullReferenceTest#470.

This won't get high priority.

However, I believe that the test against null on line 239 is not needed. Removing it gets the warning of line 248 away. (I'm not telling there is no bug here... just that this may be an appropriate work around.)

> Released inactive NullReferenceTest#470.

This test has been enabled during bug 190737.
Should we mark this as closed/duplicate of that bug?

Darin, are you still seeing the warning?
Comment 3 Olivier Thomann CLA 2011-03-04 08:43:13 EST 
Closing as a dup.
