Usually these methods are always called on the same thread.
Adding synchronized under this assumptium shouldn't add much cost (no actual contention) so I am fine with the patch.
I wonder if you found out which is the activity who accesses this object outside of the assigned ML thread

We shouldn't change the thread here, it will delay the handleBookieFailure process. Please check the failed test LedgerClose2Test#testMetadataChangedDuringClose

Gotcha!
Good job! |
* Fixed locking of PendingAddOp * Fixed stack overflow * Fixed stack overflow in different point
Motivation
Fix #3805
The test was failing because the updates to the object, done in the
initiate()
method, were not immediately visible to other threads. We must use synchronized consistently in all the accesses.
