Description Peter Lam 2006-10-10 00:55:06 UTC
using latest uml build 061009_8 on NB RC1 build on windows xp with jdk 1.6 beta2.

uninstallation hangs while uninstalling the uml module and has to kill ide using
task manager. This seems to be happening 95% of the time. See attached thread
dump. the dos window buffer is not big enough to capture the full thread dump
but has majority of the info needed.

Steps to reproduce:
- install uml nbms with manually install downloaded nbms option
- open an existing uml project containing at least a class diagram with a few
classes
- right-click in the class diagram window and select Layout->Properties...
- close the layout properties dialog
- bring up module manager
- select the UML module
- press the Uninstall button and answer Yes to the dialog to uninstall
Result: the uninstallation started to hang withing a second

uninstall uml thread dump
Comment 2 Yang Su 2006-10-10 01:03:02 UTC
In this deadlock case, we need jvm thread dump instead of ide log, please
provide the required info to help debugging.

Comment 4 Peter Lam 2006-10-10 01:04:36 UTC
when uninstallation hangs, more exceptions are in the ide log file. See
messages.log attached.
Comment 5 Peter Lam 2006-10-10 01:07:08 UTC
ops, attached wrong file for thread dump. see new attachement for thread dump
with "thread dump" as the name.
