I got this NPE by clicking the button to the left of the "stop" button in the workbench (global) debug toolbar.

Caused by: java.lang.NullPointerException

Thank you for the trace.  It implies that the action was either initialized with a null IWorkbenchWindow, or was ran after being disposed.  Did this occur in context of starting or shutting down the IDE?
Comment 2 Pawel Piech CLA 2011-10-27 18:18:59 EDT 
BTW, it's the "disconnect" action, which applies only to remote debugging in java, though it's more useful with CDT.  Do you think it should be hidden by default?
Comment 3 John Arthorne CLA 2011-10-31 14:34:23 EDT 
It wasn't at startup or shutdown, but it was immediately after I enabled the global debug toolbar for the first time. 

And yes it was the "Disconnect" action. For some reason tooltips weren't working at the time, but I see the tooltips now.

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.

If you have further information on the current state of the bug, please add it. 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.

If the bug is still relevant, please remove the "stalebug" whiteboard tag.
