Comment 1 Michael Rennie CLA 2011-10-11 14:00:09 EDT 
looks like it is caused by the Firebug bug: http://code.google.com/p/fbug/issues/detail?id=4635

exception guard

The patch acts as a guard against the exception until the proper fix is applied to the Crossfire extension.
Comment 3 Michael Rennie CLA 2012-01-10 14:40:03 EST 
Marking fixed. There is no need to keep this bug open, a fix has been applied to Eclipse to prevent the Crossfire bug.
