> [~stanleyxu2005],
> I have launched a word count example and then I replaced the split processor
> with an invalid one (I use slf-log4j.jar). I found several issues:
> # There is no error message from backend, even when the specified task class
> is not found on class path.
> # As there is no data sent from the broken processor, after couple of
> seconds, the send throughput will decrease to zero. The number of total sent
> messages will be 0. Actually the count of previous split processor is not
> taken into account.
> # The application clock becomes 9223372036854775807. The application status
> is still active.
