I think it is related to the following two threads. Worker-0 holds
workspace lock (see Workspace.endOperation line 1022) and tries to join
Worker-10. And Worker-10 is waiting for workspace lock
(Workspace.prepareOperation line 1747). The deadlock seems to be a WTP
bug, but I do not know whether it was triggered by m2e or not.

Could it be a WTP deadlock or do you think its related to WTP/m2eclipse ?

Henri,
Hi Igor
Do you have a reliable way to reproduce the deadlock which you can share
with me? I do not see anything obvious from these stack traces (m2e sits in
the IResource#deleteMarkers) and will need to reproduce this problem locally
in order to debug it.
No way.
I see this problem on both Eclipse 3.3.2 and 3.4 (and the related WTP).
My workspace is very important (about 200 projects), and now that I
mavenize them all, I see this problem more and more often and the only
solution is to rename my workspace and reimport all projects by hand
in the newly workspace.
Hope you help me
