Re: [jgit-dev] AIOOBE in DirCache.getEntry
Even with the fix for bug 457152, we are still getting similar stacktraces reported: 

java.lang.ArrayIndexOutOfBoundsException
	at org.eclipse.jgit.dircache.DirCacheTree.contains(DirCacheTree.java:404)
at org.eclipse.jgit.dircache.DirCacheIterator.parseEntry(DirCacheIterator.java:234) at org.eclipse.jgit.dircache.DirCacheIterator.parseEntry(DirCacheIterator.java:216) at org.eclipse.jgit.dircache.DirCacheIterator.next(DirCacheIterator.java:199) 
	at org.eclipse.jgit.treewalk.TreeWalk.popEntriesEqual(TreeWalk.java:953)
	at org.eclipse.jgit.treewalk.TreeWalk.next(TreeWalk.java:540)

I've commented here as well:

Looks like his .git/index was corrupted and a re-clone has fixed the
problem.

AFAIU, DirCache.entryCnt and sortedEntries.length can't become
inconsistent, so I'm wondering whether there is a problem with
DirCacheIterator.ptr which should be checked and inconsistencies handled
by an IOException?

Btw, there is no (relevant) difference in DirCache and DirCacheIterator
between stable-2.3 and stable-3 branch.
