That's true. The first message is saying that the artifact being requested is either not known to the IdP or has expired.

Peter's question about state sharing is worth answering, but other than that it would probably help if you have us more of the logs, from the first of the messages you've quoted to the second one.

Peter's also right that we'd generally regard an NPE as a bug, as they are really not very helpful in telling people what has gone wrong. In this case, I suspect the NPE is only happening because the code that delivers the first message doesn't return from the method as it should, so it's probably not relevant to diagnosing your issue. Nevertheless, I've raised a JIRA case for the NPE part of this:
