Starting up a workspace with some editors opened, I ran into the following exception. java.lang.NullPointerException at org.eclipse.m2e.jdt.internal.MavenClasspathContainerInitializer.initialize(MavenClasspathContainerInitializer.java:46) at org.eclipse.jdt.internal.core.JavaModelManager.initializeContainer(JavaModelManager.java:2810) at org.eclipse.jdt.internal.core.JavaModelManager$11.run(JavaModelManager.java:2716) at org.eclipse.core.internal.resources.Workspace.run(Workspace.java:2313) at org.eclipse.jdt.internal.core.JavaModelManager.initializeAllContainers(JavaModelManager.java:2756) at org.eclipse.jdt.internal.core.JavaModelManager.getClasspathContainer(JavaModelManager.java:1868) at org.eclipse.jdt.core.JavaCore.getClasspathContainer(JavaCore.java:2741) at org.eclipse.jdt.internal.core.JavaProject.resolveClasspath(JavaProject.java:2652) at org.eclipse.jdt.internal.core.JavaProject.resolveClasspath(JavaProject.java:2790) at org.eclipse.jdt.internal.core.JavaProject.getResolvedClasspath(JavaProject.java:1922) at org.eclipse.jdt.internal.core.JavaProject.computePackageFragmentRoots(JavaProject.java:616) at org.eclipse.jdt.internal.core.JavaProject.computePackageFragmentRoots(JavaProject.java:685) at org.eclipse.jdt.internal.core.JavaProject.computePackageFragmentRoots(JavaProject.java:649) at org.eclipse.jdt.internal.core.JavaProject.getAllPackageFragmentRoots(JavaProject.java:1393) at org.eclipse.jdt.internal.core.JavaProjectElementInfo.getProjectCache(JavaProjectElementInfo.java:206) at org.eclipse.jdt.internal.core.JavaProjectElementInfo.newNameLookup(JavaProjectElementInfo.java:290) at org.eclipse.jdt.internal.core.JavaProject.newNameLookup(JavaProject.java:2289) at org.eclipse.jdt.internal.core.SearchableEnvironment.<init>(SearchableEnvironment.java:57) at org.eclipse.jdt.internal.core.SearchableEnvironment.<init>(SearchableEnvironment.java:64) at org.eclipse.jdt.internal.core.CancelableNameEnvironment.<init>(CancelableNameEnvironment.java:26) at org.eclipse.jdt.core.dom.CompilationUnitResolver.resolve(CompilationUnitResolver.java:664) at org.eclipse.jdt.core.dom.ASTParser.internalCreateAST(ASTParser.java:1175) at org.eclipse.jdt.core.dom.ASTParser.createAST(ASTParser.java:801) at org.eclipse.jdt.internal.ui.javaeditor.ASTProvider$1.run(ASTProvider.java:543) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.jdt.internal.ui.javaeditor.ASTProvider.createAST(ASTProvider.java:536) at org.eclipse.jdt.internal.ui.javaeditor.ASTProvider.getAST(ASTProvider.java:479) at org.eclipse.jdt.ui.SharedASTProvider.getAST(SharedASTProvider.java:126) at org.eclipse.jdt.internal.ui.javaeditor.ClassFileEditor$3.run(ClassFileEditor.java:689) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)
Closing old bug reports. Please reopen if you still see the problem with final m2e 1.0 and provide new stacktrace, m2e and eclipse log files and eclipse configuration details.

I still get this intermittently but frequently.
I've also hit this, and opened a new bug 388039, as one cannot re-open issues here, and I doubt anybody is looking at this one in Status CLOSED WORKSFORME.
