Thread dump

091207-ea36fa03ce7b, JDK 6. Encountered when closing the nbbuild project. Straightforward lock ordering ambiguity. Looks to actually be two similar problems: both of these classes call foreign code while holding a monitor.

Reassigning to Tomas for evaluation.
Comment 3 Tomas Zezula 2009-12-21 05:07:58 UTC 
The second thread dump is a different problem.
It has nothing in common with DCP. It's pure freeform deadlock (ff classpath cs project mutex).
Comment 4 Tomas Zezula 2009-12-21 07:48:04 UTC 
Both deadlocks fixed.
