Eclipse plugin hangs and prevents user input until restart v2

Migrated from http://lampsvn.epfl.ch/trac/scala/ticket/3055
Reporter ijuma
Eclipse hangs during editing and it needs to be killed and restarted to fix it, tested with r20745. Part of the stacktrace is reproduced below, and the full stacktrace is attached.

Could it be that this bug somehow re-appeared.

I am using:
Eclipse: 20100218-1602
