[jira] [Created] (KAFKA-12887) Do not trigger user-customized ExceptionalHandler for RTE

Guozhang Wang created KAFKA-12887:
-------------------------------------

             Summary: Do not trigger user-customized ExceptionalHandler for RTE
                 Key: KAFKA-12887
                 URL: https://issues.apache.org/jira/browse/KAFKA-12887
             Project: Kafka
          Issue Type: Improvement
          Components: streams
            Reporter: Guozhang Wang


Today in StreamThread we have a try-catch block that captures all {{Throwable e}} and then triggers {{this.streamsUncaughtExceptionHandler.accept(e)}}. However, there are possible RTEs such as IllegalState/IllegalArgument exceptions which are usually caused by bugs, etc. In such cases we should not let users to decide what to do with these exceptions, but should let Streams itself to enforce the decision, e.g. in the IllegalState/IllegalArgument we should fail fast to notify the potential error.
