Right, we have not yet implemented shallow client support in JGit.
The way to do handle the shallow stuff is to actually insert
pre-parsed RevCommit objects into the RevWalk object pool that have
the parents truncated away, similar to a graft (which we also don't
support). This will keep JGit from walking backwards into the commits
it doesn't have, and thus avoid the MissingObjectException you noted.
That isn't a complete solution, the transport code also needs to know
how to fetch into a shallow repository. But it would certainly help to
fix RevWalk so its not crashing.
