stack dump

SDK 3.8 Build id: I20120125-1800

In the background JUnit Plug-in Tests were running.
I was trying to continue browsing code and expanding items in the JUnit view.
I think it was at the expand click that the busy cursor appeared, and Eclipse froze. I killed the debug target, but still Eclipse would not unfreeze.

Attaching stack traces after killing the debug target. A few debug related threads had disappeared by then but the following threads have not changed since the freeze:
"Worker-79"
"Worker-73"
"main"
all of which are interested in the same lock object.

Although I see a key event in the stack I can't recall using the keyboard at that time but recollection is blurred by the fact that I was also switching virtual desktops and just came back to Eclipse at what time it wouldn't respond to the next click.

first stack dump

OK, I also have a dump from when the debugger was still running. Most threads show no difference between both dumps.
