| [cdt-dev] Deadlock using 3.0 branch |
|
I just ran into this deadlock - stack trace is below. We
have 2 threads waiting to enter PathEntryManager.getPathEntryStore, which uses
the Java synchronized keyword. The other thread is inside that routine
waiting for a lock of some kind. This other thread has caused the MBS
plugin to be started and the MBS has called: IJobManager
jobManager = Platform.getJobManager(); IWorkspaceRoot
root = ResourcesPlugin.getWorkspace().getRoot(); try
{ jobManager.beginRule(root,
null); startResourceChangeHandling(); }
catch (Exception e) {… startResourceChangeHandling calls: ISavedState
lastState = ResourcesPlugin.getWorkspace().addSaveParticipant(ManagedBuilderCorePlugin.this,
listener); Anyone have any ideas? Thanks, Leo ======================================================= Thread [main] (Suspended) PathEntryManager.getPathEntryStore(IProject,
