Starting up a workspace with some editors opened, I ran into the following exception.

Closing old bug reports. Please reopen if you still see the problem with final m2e 1.0 and provide new stacktrace, m2e and eclipse log files and eclipse configuration details.

I still get this intermittently but frequently.

I've also hit this, and opened a new bug 388039, as one cannot re-open issues here, and I doubt anybody is looking at this one in Status CLOSED WORKSFORME.
