Ignore my comment about different thread, I see that timeoutQuorumWait() is run through OSE. But we did NPE in this line <https://github.com/apache/bookkeeper/blob/master/bookkeeper-server/src/main/java/org/apache/bookkeeper/client/PendingAddOp.java#L173>. In this run, we have disabled ensemble changes.
