> Global stream thread ignores all exceptions
> -------------------------------------------
>
> Key: KAFKA-19724
> URL: https://issues.apache.org/jira/browse/KAFKA-19724
> Project: Kafka
> Issue Type: Bug
> Components: streams
> Affects Versions: 3.4.0
> Reporter: Mikołaj Bul
> Assignee: Fatih Celik
> Priority: Major
> Labels: beginner, newbie
>
> {{globalStreamThread}} in {{KafkaStreams}} class ignores all exceptions and
> fails to apply the user-provided {{StreamsUncaughtExceptionHandler}} in:
> {code:java}
> public void setUncaughtExceptionHandler(final StreamsUncaughtExceptionHandler
> userStreamsUncaughtExceptionHandler)
> {code}
> This can lead to streams being stuck in faulty state after an exception is
> thrown during their initialization phase (e.g. failure to load the RocksDB
> native library). The exception isn't logged, so debugging such problem is
> difficult.
> From my understanding of the {{b62d8b97}} commit message, the following code
> is unnecessary as the {{globalStreamThread}} can't be replaced and the issue
> description from KAFKA-12699 doesn't apply to it. Removing it should help.
> {code:java}
> if (globalStreamThread != null) {
> globalStreamThread.setUncaughtExceptionHandler((t, e) -> { }
> );
> }
> {code}
