I need assistance from the JDT CORE team for the debug "hang". Looking at the attached thread dump, it looks like the following has happened:

* the debug view has handled a suspend event, and is trying to open an editor on the associated compilation unit, in the "main thread"
* the test has made changes to the same compilation unit, and is saving the changes (testing HCR), in the "test thread"
* the (saved) changes to the compilation unit, have caused the UISyncronizer to do a sync exec (i.e. waiting on the main thread). This thread has a lock on the compilation unit that has been changed
* the main thread is waiting for a lock on the same compilation unit (trying to open it).

-> deadlock

Subject: [eclipse-dev] JUnit test results for build N20031006 (Timestamp: 200310060010)

The rerun of the tests for build N20031006 resulted in the JDT Debug tests "hanging" on both Windows and Linux and the Ant UI tests failing on Linux (see attached).

Ant and Debug teams, please let me know if my assistance is required to troubleshoot these any further.

There were a number of problems running the nightly builds over the weekend due to a number of defunct processes and hung tests in JDT Debug and JDT Core. I will rerun all tests for N20031006 and send thread dumps/results to this list.
