Motivation
It's possible to get into a situation where there are multiple topic instances for the same topic getting unloaded and loaded in the same broker concurrently.
A solution for addressing this problem was introduced in #17526.
However, the solution was removed in #17736 since the call
brokerService.removeTopicFromCache(PersistentTopic.this)was replaced with the callbrokerService.removeTopicFromCache(topic)since there was the old method signature available in the class.Modifications
