Looks like this is fixed with fix for bug 468134.
(In reply to Andrey Loskutov from comment #1) > Looks like this is fixed with fix for bug 468134. No, the lines are changed (line 47 now) but NPE is still possible: RepositoryMapping.getMapping can return null and should not be directly dereferenced.
