Description Antonin Nebuzelsky 2005-12-13 22:44:28 UTC 
When profiling New Action apisupport wizard, I found out that there is
org.openide.explorer.ExplorerManager and related objects leaking via the
following reference path:

  sun.awt.X11.XToolkitThreadBlockedHandler.tk->
  sun.awt.X11.XToolkit@18e2b22->
  java.awt.Toolkit$ToolkitEventMulticaster@1d9d839->
  java.awt.Toolkit$ToolkitEventMulticaster@1cf633f->
  java.awt.Toolkit$SelectiveAWTEventListener@68b475->
  org.openide.util.AsyncInitSupport@1e356a5->
  org.netbeans.modules.project.ui.TemplateChooserPanelGUI@1636bbf->
  org.netbeans.modules.project.ui.TemplatesPanelGUI@11c7768->
  org.netbeans.modules.project.ui.TemplatesPanelGUI$CategoriesPanel@18d21f->
  org.openide.explorer.ExplorerManager@8b063

Debugging the code in AsyncInitSupport I realized that it attaches the
AWTEventListener in its constructor, but its method eventDispatched() never gets
through the condition

  SwingUtilities.isDescendingFrom(comp4Init, (Component) (event.getSource()))

and thus detach() called in start() is never run. The reason is IMHO that the
TemplatesChooserPanelGUI never gets inside NbDialog instance which is here as
the value of event.getSource().

I am not sure where the fix should be. I want to talk to Jirka about it, but I
believe this issue belongs to org.netbeans.modules.project.ui.

Changing summary from
  NewFileWizard leaks ExplorerManager if run with predefined file type
to
  NewFileWizard leaks TemplateChooserPanelGUI if run with predefined file type
because
TemplateChooserPanelGUI is the closest object to where the leak is held (the
nondetached AWTEventListener). However, the summary of the issue is not
important, the leak is what matters here. :)
