I cannot reproduce this bug. I've tried opening added, remove and changed files from both workspace and git change set presentations model and this NPE didn't occur. Can you provide mode detailed steps for reproducing this issue?
I've got the same stack trace when ttrying to do "Close Others" or File->Close All.. I too have EGit Compare in use, and since that is too buggy to even report bugs on, I guess EGit is the problem. For instance, single clicking in the EGIT Tree Compare that only show the first of a multi-selection for compare, does nothing. Double clicking shows two compare editors, if don't re-use compare edirtor is selected. If re-use compare editor is selected you just wonder waht on eartyh is happening and desparately look for the missing context menu and toolbar icons. Compare itself is significantly different to normal compare, so ... Just tried closing some editors. One wouldn't close; same stack trace. It was dirty. Saved it, now closes. I suspect a dirty EGIT Compare may be the clue.
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.
