Comment 1 Philipe Mulet CLA 2005-04-19 06:04:04 EDT 
Ignoring initial classloader circularity (could be a PDE issue), problem comes
from interference between one editor reconciling while package explorer is being
rendered.

Reconcile
 - lock on projectElementInfo (to compute namelookup)
 - initializes classpath
 - calls out client CP initializer
 - execute operation which needs resource lock --> WAIT

Main (pkg explorer)
 - takes resource lock
 - initializes classpath 
 - attempt to lock on projectElementInfo to reset pkg fragment roots cache
 - DEADLOCK
Comment 2 Philipe Mulet CLA 2005-04-19 06:04:51 EDT 
No 3rd party code should run within our projectElementInfo lock. 
Proposal is to stop synchronizing namelookup creation.
Comment 3 Jerome Lanneluc CLA 2005-04-19 07:13:40 EDT 
Changed JavaProjectElementInfo to use a member class (ProjectCache) to store the
allPackageFragmentRootsCache, allPackageFragmentsCache, and
pathToResolvedEntries. This cache is reset at once (by nulling the projectCache
field), and it is initialized at once (in getProjectCache()). No need to
synchronize these methods any longer.

Verified for 3.1 M7 using build I20050509-2010 + jdt.core HEAD.
