I'm running the m4 release of NB 6.0 on Sun Solaris 9. When I expand the Package View, I get the following exception java.util.ConcurrentModificationException at java.util.TreeMap$PrivateEntryIterator.nextEntry(TreeMap.java:1031) at java.util.TreeMap$KeyIterator.next(TreeMap.java:1058) at org.openide.nodes.Children$Dupl.updateList(Children.java:2207) at org.openide.nodes.Children$Keys.setKeys(Children.java:2000) at org.netbeans.spi.java.project.support.ui.PackageViewChildren.refreshKeys(PackageViewChildren.java:202) at org.netbeans.spi.java.project.support.ui.PackageViewChildren.access$000(PackageViewChildren.java:92) [catch] at org.netbeans.spi.java.project.support.ui.PackageViewChildren$1.run(PackageViewChildren.java:211) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209) at java.awt.EventQueue.dispatchEvent(EventQueue.java:461) at java.awt.EventDispatchThread.pumpOneEventForHierarchy(EventDispatchThread.java:242) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:163) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:157) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:149) at java.awt.EventDispatchThread.run(EventDispatchThread.java:110) It continues populating. This looks similar to Issue # 88589. My java version is java version "1.5.0_09" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_09-b03) Java HotSpot(TM) Server VM (build 1.5.0_09-b03, mixed mode) And I am viewing my package contents as a List (not a Tree).
Reassigning to "openide" for eval
Are you running on a multi-cpu machine? (Dual-core, hyper-threading, or real SMP?)
Definately mulitple cpu (4, I think). However, pretty sure it's not Dual-core, hyper-threading or real-SMP. It's running on a Sun Sparc box. Here's the output from uname.... ehillman@wallaby:> uname -a SunOS wallaby 5.9 Generic_118558-30 sun4u sparc SUNW,Sun-Fire-V440
Randomly getting this exception while merging project sources on Win Xp, Duo Core CPU. NetBeans IDE Dev (Build 200611290115) 1.6.0-rc; Java HotSpot(TM) Client VM 1.6.0-rc-b101 Windows XP version 5.1 running on x86 en_GB (nb); Cp1252
Updating platform. So this problem is definitely not related to the multi-core bug that was in Mutex a month ago...

moving opened issues from TM <= 6.1 to TM=Dev
Is it still valid problem? It was not reported for a long time. Closed as worksforme. If appear again, I prefer to report it again via Exceptions reporter which can watch all duplicates that problem. Thanks
