This was due to the merge with https://github.com/openjdk/jdk/commit/fbc4691bfa11f31601fd89d05da63e689343e214, I resolved the conflict in the test but missed that the change adds a new `AbstractImmutableMap` implementation, and the `keySet` doesn't throw UOE on modifications. I have an initial changes that has MOAT passing again, but that part may require more thought.

Thanks, that sounds great!
