Description
PersistenceManager.addSegments returns a CompletionStage which should be completed on a persistence executor thread. If the persistence executor was already stopped at the time addSegments() was called, however, the CompletionStage is never completed.
This doesn't prevent the cache manager from stopping, but it causes a thread leak because a transport thread waits forever on the CompletionStage. E.g.
