JsonDeserialize on case class constructor argument not working from Java... sometimes

This is an interesting test case, I'll have to digest it a bit to figure out how to approach it. To comment on a couple of issues, yes I believe there is some static caching that happens in core Jackson that might be available across ObjectMapper instances to explain some of the behavior.

As for the java/scala behavior differences, my current working theory would be that the scala code does some additional classloading that's not done by the java code, that allows the ObjectMapper to find the deserializer; but that's pretty far fetched at this point, and I won't know more until I have a chance to write some Java tests and step through the code.

I've got some hefty refactoring to do in the codebase for 2.2 that needs to happen first; with luck issues like this will be taken care of along the way, but if it isn't I'll take a look at this when I'm closer to release time.

I've added a test case for this and it appears to be passing now. If you're still having trouble using 2.2.0-SNAPSHOT, I'll reopen it.
