Guozhang Wang commented on KAFKA-12887:
---------------------------------------

Hello [~icorne] We have reverted this change due to reasons similar to what you 
described here. Do you see it still in 3.1.1? Could you try 3.2.1 instead?

> Do not trigger user-customized ExceptionalHandler for RTE

> 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.
