Deadlock

jstack output

Some kind of lock ordering conflict. I had a POM open in one IDE; launched a second instance, in which I edited the POM (ultimately reverting it); then closed the second instance, giving focus back to the first.

Deadlock

Happened again in 100719.
Comment 3 Jesse Glick 2010-07-19 13:16:39 UTC
Happened to me again when switching back to an IDE after having edited an open POM in an external editor. Clear lock ordering conflict, needs to be fixed.
Comment 4 Jesse Glick 2010-07-19 16:33:32 UTC
...and again (no POM open this time).

Comment 6 Jesse Glick 2010-07-30 19:42:08 UTC
Recurring problem, potentially leading to data loss. Reported in 6.9.1 so may be worth backporting.
Comment 7 Jesse Glick 2010-08-02 15:44:34 UTC
Easily reproducible: open Maven project; open pom.xml in IDE editor; from an external editor, make some edit e.g. to <name> and save; switch back to IDE.

Simple fix seems to be to force the reload to be processed before synching model. Probably does not prevent every possible occurrence but straightforward and should be safe. core-main #463572b0a8ef

Integrated into 'main-golden', will be available in build *201008030001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)

Are there any 6.9.x updates still being released? This would be a prime candidate.

verified in 6.9 patch 2
Comment 19 jcrim 2010-10-22 17:46:50 UTC
I'm running 6.9.1.  What's the best way for me to get this issue patched?  This is a major issue that was found 4 months ago and has been fixed for 2.5 months, so I find it disturbing that no updates have been issued for the most current release version.

Wait for the patch to be released.
