Every time I open my projects I get messages about these Duplicate pairs. Also when viewing some of the options, anything that refers to the Debugger or Compilation setting displays the message about "Duplicate pair in treePair1" in red, along with a heap of exception pop-ups. This is currently making my project unusable... java.lang.IllegalStateException: Duplicate pair in treePair1: SL[/Hidden/Versioning Settings pair2: SL[/Hidden/Versioning Settings index1: 39 index2: 39 item1: org.netbeans.modules.vcscore.settings.GeneralVcsSettings@d5c653 item2: org.netbeans.modules.vcscore.settings.GeneralVcsSettings@d5c653 id1: 1da0a1 id2: 11cab1c at org.openide.util.lookup.ALPairComparator.compare(ALPairComparator.java:52) at java.util.TreeMap.compare(TreeMap.java:1085) at java.util.TreeMap.put(TreeMap.java:463) at java.util.TreeSet.add(TreeSet.java:209) at org.openide.util.lookup.AbstractLookup$R.initItems(AbstractLookup.java:788) at org.openide.util.lookup.AbstractLookup$R.allItemsWithoutBeforeLookup(AbstractLookup.java:749) at org.openide.util.lookup.AbstractLookup$R.allInstances(AbstractLookup.java:691) at org.openide.util.lookup.ProxyLookup$R.computeResult(ProxyLookup.java:369) at org.openide.util.lookup.ProxyLookup$R.allInstances(ProxyLookup.java:320) at org.openide.util.lookup.ProxyLookup$R.computeResult(ProxyLookup.java:369) at org.openide.util.lookup.ProxyLookup$R.allInstances(ProxyLookup.java:320) at org.openide.util.SharedClassObject.findObject(SharedClassObject.java:484) at org.netbeans.modules.vcscore.VcsFileSystem.<init>(VcsFileSystem.java:1789) at org.netbeans.modules.vcs.advanced.CommandLineVcsFileSystem.<init>(CommandLineVcsFileSystem.java:233) at org.netbeans.modules.vcs.advanced.CommandLineVcsFileSystem.<init>(CommandLineVcsFileSystem.java:205) at org.netbeans.modules.vcs.advanced.wizard.mount.MountWizardIterator.initialize(MountWizardIterator.java:76) at org.openide.loaders.TemplateWizardIterImpl.setIterator(TemplateWizardIterImpl.java:67) at org.openide.loaders.TemplateWizard.setTemplateImpl(TemplateWizard.java:172) at org.openide.loaders.TemplateWizard.setTemplate(TemplateWizard.java:190) at org.openide.loaders.TemplateWizard.instantiateImpl(TemplateWizard.java:392) at org.openide.loaders.TemplateWizard.instantiate(TemplateWizard.java:358) at org.openide.actions.NewTemplateAction$TemplateActionListener.acceptNodes(NewTemplateAction.java:540) at org.openide.explorer.view.MenuView$MenuItem.doClick(MenuView.java:445) at javax.swing.plaf.basic.BasicMenuItemUI.doClick(BasicMenuItemUI.java:1113) at javax.swing.plaf.basic.BasicMenuItemUI$MouseInputHandler.mouseReleased(BasicMenuItemUI.java:943) at java.awt.Component.processMouseEvent(Component.java:5100) at java.awt.Component.processEvent(Component.java:4897) at java.awt.Container.processEvent(Container.java:1569) at java.awt.Component.dispatchEventImpl(Component.java:3615) at java.awt.Container.dispatchEventImpl(Container.java:1627) at java.awt.Component.dispatchEvent(Component.java:3477) at java.awt.LightweightDispatcher.retargetMouseEvent(Container.java:3483) at java.awt.LightweightDispatcher.processMouseEvent(Container.java:3198) at java.awt.LightweightDispatcher.dispatchEvent(Container.java:3128) at java.awt.Container.dispatchEventImpl(Container.java:1613) at java.awt.Window.dispatchEventImpl(Window.java:1606) at java.awt.Component.dispatchEvent(Component.java:3477) [catch] at java.awt.EventQueue.dispatchEvent(EventQueue.java:456) at java.awt.EventDispatchThread.pumpOneEventForHierarchy(EventDispatchThread.java:201) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:151) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:145) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:137) at java.awt.EventDispatchThread.run(EventDispatchThread.java:100)
I've gone through some of the similar issues marked as resolved, but they all have something to do with web browsers - I don't seem to have quite the same problem. There is a workaround for the web browser problem, looks like it involves deleting user files and restarting, but I don't see a workaround (or an indication of what files to delete) for my version of the issue.
They all ahd comething with broken lookup implementation. The problem is fixed in current NB and AFAIK no fix is planed for 3.6 *** This issue has been marked as a duplicate of 40364 ***
