>             Project: Kafka
>          Issue Type: Bug
>          Components: streams

> Streams uses multiple internal client that might throw fatal exceptions (some should actually never occur, and if, this would indicate a bug).
> We should wrap all calls to the used clients with a {{try-catch}}, and log those exceptions as ERRORs immediately. For exceptions that can only occur due to a bug (e.g., IllegalStateException, IllegalArgumentException, WakeupException, InterruptException) we should ask users in the log message to report this as a bug.
> Last, we rethrow all those exceptions as {{StreamsException}} (to avoid that a standard library exception might be caught by accident somewhere else in our code base).
