Hi Jorn,

The problem most likely due to the prior Runtime exception. Is there
a stack trace for that? Is the CasMultiplier doing anything strange,
like calling cas.reset()?

The exception occurs before getEmtpyCas is call, no there is
no cas.reset() call.

There is mistake in the log statement, because the second message
contains {0}.

Can you send the full stack trace for the other exception?

I think the exception gets logged three times and afterwards
there is the log message of the mentioned warning.
The error repeats a few times, not sure if thats really
the one which causes the hang.

Do you think there is a mistake in the implementation of my Cas Multiplier ?
