Description David Konecny 2008-04-17 08:13:32 UTC

I've seen it once; I do not know how to reproduce it; after IDE startup I expanded project node.

The problem seems to be that  "Java Source Worker Thread" holds source.usages.ClassPathRootsListener lock and waits for
project.readAccess and "Load Open Projects" holds project.writeAccess and waits on source.usages.ClassPathRootsListener.
A solution could be (although I'm not sure it logically make sense because I have no idea what java.source module does)
for RepositoryUpdater.registerClassPath to request project.readAccess first.
