It is a deadlock among MergedClassPathImplementation and Project's mutex. It has to be probably solved in the MergedClassPathImplementation. Other possibility is to order the locks, this is uglier solution but if it will be hard to do it in the MergedClassPathImpl I can try this. I can help you with this bug.
Javacore module was replaced by Retouche infrastructure. This bug is not valid in trunk any more.
