[refactoring build 040505; JDK 1.4.2_04] I had one project open, and tried to open another one (created using a trunk build a couple days ago). The project node appeared in the Projects View and the 'Applying Paths' progress bar appeared. However, no progress was shown and the IDE deadlocked (thread-dump attached).

I suppose you did this after you had unsuccessfuly deleted a file (issue 42877). It looks like transaction did not finish after unsuccessful delete.
If that would be the case, then it would mean that there is a code somewhere that starts the transaction but does not end it in finally clause.
Re Jan Becicka: Quite possible. I'll try to reproduce one or the other.
Already fixed in ExclusiveMutex. Transaction was not ended correctly due to Exception thrown due to 42877. Transaction is now ended in finally clause.
Verified (as part of issue #42877).
