Comment 1 Daniel Prusa 2010-02-08 02:49:24 UTC

It does not look like a problem in debugger. NPE is caused by a null stored as a value of an entry in a map returned by IndexingController.getDefault().getRootDependencies(). The map is obtained in SourceUtils.getDependentRoots(URL) and passed as a parameter to SourceUtils.getDependentRootsImpl(URL, Map<URL, List<URL>>).
Reassigning for evaluation.

Duplicate of bug #177763, thanks for the report anyway.
