Because it takes some time for the error to occur I don't have much traces.
Sorry, but there's nothing more.
It's cool that you're trying to help me with this old cayenne version. Thank
you very much!

Could you send the full stack trace for this NullPointerException? Or
is it trimmed from the overall stack? Newer versions of Cayenne are
better in this respect - in all (?) cases Cayenne would show the
underlying exception that caused a chain of exceptions downstream.
