Well, for starters `git tag --contains` is probably just a wrapper
around `git name-rev`, which we haven't actually implemented yet in
JGit. But your brute force approach can try to approximate it... more
slowly.

Why are you setting these on the RevWalk?

                walk.setTreeFilter(TreeFilter.ANY_DIFF);

This shouldn't be necessary... but is also unsupported. Asking for
differences between a commit and its parent when you are also looking
for a merge base isn't something we ever planned to do.

                walk.sort(RevSort.TOPO, true);
                walk.sort(RevSort.COMMIT_TIME_DESC, true);

These sorts are unnecessary, the merge base code ignores them and
should process the graph itself without these.

That said, your test is looking for a merge base of a commit with
itself, which is itself. Looking over MergeBaseGenerator, this should
be working. :-(
