This behavior was observed when running various tests:
* {{ZooKeeperCheckpointIDCounterITCase.testShutdownRemovesState}}
* {{ZooKeeperStateHandleStoreTest.testAddAndLock}}
* {{ZooKeeperStateHandleStoreTest.testFailingAddWithPossiblyInconsistentState}}

I'd assume that this applies in any other case as well.
