Using RC1, I got this running some JUnit plugin tests. java.lang.NullPointerException at org.eclipse.jdt.internal.core.search.indexing.IndexManager.shutdown(IndexManager.java:509) at org.eclipse.jdt.internal.core.JavaModelManager.shutdown(JavaModelManager.java:1535) at org.eclipse.jdt.core.JavaCore.shutdown(JavaCore.java:2986) at org.eclipse.core.internal.plugins.PluginRegistry$2.run(PluginRegistry.java:283) at org.eclipse.core.internal.runtime.InternalPlatform.run(InternalPlatform.java:867) at org.eclipse.core.internal.plugins.PluginRegistry$1.visit(PluginRegistry.java:296) at org.eclipse.core.internal.plugins.PluginRegistry.accept(PluginRegistry.java:55) at org.eclipse.core.internal.plugins.PluginRegistry.shutdownPlugins(PluginRegistry.java:299) at org.eclipse.core.internal.plugins.PluginRegistry.shutdown(PluginRegistry.java:265) at org.eclipse.core.internal.runtime.InternalPlatform.loaderShutdown(InternalPlatform.java:517) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.eclipse.core.internal.boot.InternalBootLoader.shutdown(InternalBootLoader.java:979) at org.eclipse.core.internal.boot.InternalBootLoader.run(InternalBootLoader.java:850) at org.eclipse.core.boot.BootLoader.run(BootLoader.java:431) at EclipseRuntimeLauncher.main(EclipseRuntimeLauncher.java:24) It seems to happen when the tests run really fast and the index manager doesn't have time to start before it has to shutdown. Steps to reproduce: Run the test suite RunAllJDOMTests using RC1. It happens all the time on my machine.
Offending line is: for (int i = 0, indexesFilesLength = indexesFiles.length; i < indexesFilesLength; i++) { Added null check on indexesFiles (which can be null in some occasions).
Fixed
Verified.
