Build Identifier: 20110615-0604 When trying to open an XML-file in the XML-editor eclipse hangs. According to visualVM a Thread blocks the system. After killing Eclipse and restarting there was the following in what should be the editor window: org.eclipse.ui.PartInitException: Cannot instantiate input element factory org.jboss.tools.common.core.resources.XModelObjectEditorInputFactory for editor id=org.jboss.tools.hibernate.ui.xml.editor.Hibernate3CompoundEditor name=Player.hbm.xml at org.eclipse.ui.internal.EditorReference.getRestoredInput(EditorReference.java:398) at org.eclipse.ui.internal.EditorReference.getEditorInput(EditorReference.java:365) at org.eclipse.ui.internal.EditorReference.createPartHelper(EditorReference.java:594) at org.eclipse.ui.internal.EditorReference.createPart(EditorReference.java:465) at org.eclipse.ui.internal.WorkbenchPartReference.getPart(WorkbenchPartReference.java:595) at org.eclipse.ui.internal.EditorAreaHelper.setVisibleEditor(EditorAreaHelper.java:271) at org.eclipse.ui.internal.EditorManager.setVisibleEditor(EditorManager.java:1459) at org.eclipse.ui.internal.EditorManager$5.runWithException(EditorManager.java:972) at org.eclipse.ui.internal.StartupThreading$StartupRunnable.run(StartupThreading.java:31) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:135) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:4140) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3757) at org.eclipse.ui.application.WorkbenchAdvisor.openWindows(WorkbenchAdvisor.java:803) at org.eclipse.ui.internal.Workbench$33.runWithException(Workbench.java:1595) at org.eclipse.ui.internal.StartupThreading$StartupRunnable.run(StartupThreading.java:31) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:135) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:4140) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3757) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2604) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2494) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:674) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:667) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:123) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:344) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) Reproducible: Always Steps to Reproduce: 1.Start Eclipse 2. double click an XML-file 3.

As well as the name of the editor you're trying to use.
I also had this sometimes and somehow the problem is the WTP. I never tracked it down but I had the feeling that the problem happens if your internet connection is down and your xml references a none locale DTD. But like Remy said provide more info about the Thread hanging!

This can certainly happen with XML schema based files that reference certain XML schema namespaces, it will go and try to resolve them using the Internet (hitting the W3C site), and sometimes even if the Internet is working, there will be a significant delay accessing the site. I think there is a catalog facility in the XML editing stuff that can be used to point these XML schema files to a local copy.

Please feel free to reopen this bug when you get a thread dump from Visual VM when Eclipse has hung.
I imported eclipse dl4j getting start example and had the same problem
