The thread running org.netbeans.modules.project.ui.ProjectTab seems to take 12s of 12s execution. There seems to be one call to org.openide.loaders.FolderChildren.getNodes() 100.0 12 818 ms (100%) 12 818 ms 1 which then leads to many calls to org.openide.nodes.Children.getNodes() 51.35032 6 582 ms (51,4%) 6 582 ms 314 Possibly bug in lazy node children. One call to org.openide.loaders.FolderChildren.getNodes() 100.0 12 818 ms (100%) 12 818 ms 1 leads to 314 calls to org.openide.nodes.Children.getNodes() 51.35032 6 582 ms (51,4%) 6 582 ms 314 *** Bug 215686 has been marked as a duplicate of this bug. *** Probably the same issue in tests http://hudson4qe.cz.oracle.com/view/Trunk-QE/job/CV-multi-UI/629/jdk=JDK%207,label=ubuntu/testReport/org.netbeans.test.ide/IDECommitValidationTest/testProjectsView/?
