> The {{LeaderChangeStateCleanupTest.testStateCleanupAfterListenerNotification}} fails spuriously on Travis because of a {{NullPointerException}}. The reason is that it's not properly waited until the {{ResourceManager}} has been started. Due to this, it can happen that a leader notification message is tried to be sent to a {{LeaderRetrievalListener}} which has not been set by the {{ResourceManager}}.
