Version: 4.1.0 Build id: I20110915-0200 I'm trying to run a Runtime Workbench from both a new launch configuration and an already existing launch configuration, and it won't start. Here are some of the stack traces which it presents to me. !ENTRY org.eclipse.e4.ui.workbench 4 0 2011-09-15 10:35:03.425 !MESSAGE !STACK 0 org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: java.io.FileNotFoundException: /LegacyIDE.e4xmi at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.handleDemandLoadException(ResourceSetImpl.java:315) at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.demandLoadHelper(ResourceSetImpl.java:274) at org.eclipse.emf.ecore.resource.impl.ResourceSetImpl.getResource(ResourceSetImpl.java:397) at org.eclipse.e4.ui.internal.workbench.ResourceHandler.loadResource(ResourceHandler.java:187) at org.eclipse.e4.ui.internal.workbench.ResourceHandler.loadBaseModel(ResourceHandler.java:167) at org.eclipse.e4.ui.internal.workbench.ResourceHandler.loadMostRecentModel(ResourceHandler.java:236) at org.eclipse.e4.ui.internal.workbench.swt.E4Application.loadApplicationModel(E4Application.java:351) at org.eclipse.e4.ui.internal.workbench.swt.E4Application.createE4Workbench(E4Application.java:215) at org.eclipse.ui.internal.Workbench$3.run(Workbench.java:528) ...

DJ had org.eclipse.platform from HEAD in his workspace so PDE was picking that up (we need the R4_HEAD branch of that project instead). Closing it fixed the problem for him. One might argue that it should pick up the e4xmi file from org.eclipse.ui.workbench instead but I'm not entirely convinced this is reasonable at the moment because it doesn't make sense for someone to have the 4.x fork of org.eclipse.ui.workbench with a 3.x org.eclipse.platform. Closing as WORKSFORME.
