Huh. That should have worked.
TreeWalk.forPath returns null if the path doesn't get found. So
it sounds like jgit isn't matching the path. Its a pretty simple
operation, I'm not sure why its failing here. I'd run it through
a debugger to try and see why the TreeWalk didn't match your path.
Your code is logically the same as:
git rev-parse HEAD:$path
so it should find the blob if Git would have found it.
