Bug 367221

Description Stephan Herrmann 2011-12-20 12:07:06 EST

When running JDT/Core tests in the IDE I intermittently see some
exceptions in JavaProjectTests, not sure it's always the same,
but this time I see this in testPackageFragmentRootNonJavaResources8:

java.lang.IllegalArgumentException: Element not found: /.org.eclipse.jdt.core.external.folders/.link9.

Running just JavaProjectTests several times I could not reproduce.
