I am seeing a test appear to hang in the 1204 build when I close a project. The project close eventually invokes discardJobs which sits in a tight loop calling Thread.sleep(50) with no apparent guarantee that the loop will ever exit. The close operation is occurring on the UI (main) thread.
Any steps to reproduce the problem. Also a thread dump (of the Java Indexing thread) would help.
The problem occurs in JUnit tests that create, test and then close a significant (over 400 but the problem manifests after less than half that) number of Dynamic Web Project, which in this case are Java 5 projects create using the WTP facet mechanism.

It would be also helpful to activate the IndexManager trace to give us some more clues and have a chance to figure out what happens there. Could you use '-consoleLog -debug <dir>/.options' arguments in your eclipse command line after having added/modified the following lines in the .options file: # Turn on debug tracing for org.eclipse.jdt.core plugin org.eclipse.jdt.core/debug=true # Reports background indexer activity: indexing, saving index file, index queries org.eclipse.jdt.core/debug/indexmanager=true Then, in the DOS Command windows, copy the console outputs, paste them in a file and attach this file to this bug. TIA
(In reply to comment #2) This is a thread dump of the 'main' thread. I would need a thread dump of the 'Java indexing' thread.
Created attachment 84999 [details] Result of enabling debug tracing on the index manager when reproducing the (apparent) deadlock on the UI thread.
Created attachment 85000 [details] Traces of UI and both IndexManager threads from the debugger.
It looks like the code you are running has been modified: it calls JavaProject.getJSDTScopeFile() which doesn't exist in the 1204 build. Closing as invalid. Please reopen if you reproduce with a pure Eclipse build.
