There was a bug in the previous implementation where the BrokerClient would deregister a topic as soon as a specific key didn't have any listeners, ignoring the fact that other keys might be listening on the same topic. In tea this caused errors, because our clients then tried to access topics that were errorneously removed. This PR fixes the logic to only deregister a topic when there actually are no listeners for any keys. It also moves this handling of keys and topics into the
TopicMetadataclass so that theBrokerClientdoesn't have to deal with it anymore.Additionally, a bug/error caused by recursive BrokerClient destruction has been fixed, and some additional logging added. The Log4j config has been adjusted to actually allow those logs to be processed; previously, Log4j would use its own shutdown hook and stop logging anything once shutdown is initiated, meaning we didn't see the aforementioned errors and logs during destruction.
