(In reply to Marcel Bruch from comment #20) > Moving to jdt for review. All errors are reported by the very same person. > So I think it might be a problem of a specific piece of code Jay, given how may times this is being hit, we should backport https://bugs.eclipse.org/bugs/show_bug.cgi?id=444772 quickly and have it validated.
Same as bug 444772 *** This bug has been marked as a duplicate of bug 444772 ***
