The Eclipse log shows NullPointerException, either at startup or later. Here is the one at startup: !ENTRY org.eclipse.core.jobs 4 2 2008-05-23 15:25:55.615 !MESSAGE An internal error occurred during: "Initializing Java Tooling". !STACK 0 java.lang.NullPointerException at org.jboss.ide.eclipse.as.classpath.core.ejb3.EJB3ClasspathContainer.getClasspathEntries(EJB3ClasspathContainer.java:113) at org.eclipse.jdt.internal.core.JavaModelManager.containerPutIfInitializingWithSameEntries(JavaModelManager.java:547) at org.eclipse.jdt.internal.core.SetContainerOperation.executeOperation(SetContainerOperation.java:49) at org.eclipse.jdt.internal.core.JavaModelOperation.run(JavaModelOperation.java:720) at org.eclipse.core.internal.resources.Workspace.run(Workspace.java:1797) ....
