             Summary: Should validate uploaded JAR
                 Key: GEARPUMP-96
                 URL: https://issues.apache.org/jira/browse/GEARPUMP-96
             Project: Apache Gearpump
          Issue Type: Improvement

            Priority: Minor


imported from [https://github.com/gearpump/gearpump/issues/1437] on behalf of [~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.
