thread dump

Product Version: NetBeans IDE 6.9 (Build 201007282301)
Java: 1.6.0_24; Java HotSpot(TM) Client VM 19.1-b02

Having a Subversion Maven project I did some modifications of .pom in the editor. Later I reverted changes with Subversion/Revert action on pom's tab and then the IDE got frozzen. See the attached thread dump.

Dup of issue #185925?
Comment 3 Jesse Glick 2011-05-23 13:45:54 UTC
Fix should be in 6.9 patch 2.

Help->About read NetBeans IDE 6.9 (Build 201007282301) but I have updated IDE through the Auto Update thus I cannot say what hg revision it is based on. org.netbeans.modules.maven.hints.jar lists 

OpenIDE-Module-Implementation-Version: 201011082200

OpenIDE-Module: org.netbeans.modules.maven.hints/1

OpenIDE-Module-Specification-Version: 1.8.2


Is it 6.9 patch 2 or not? Thanks

> Is it 6.9 patch 2 or not?

Sorry, I do not know; without an Hg ID, only RE/QE can say.

Anyway we are not looking at 6.x Maven bugs any more; too much changed in 7.0 for that to be worthwhile.
