I have never seen this error, no.
I guess refining the removalListener would help.

Though we couldn't reproduce the issue , we doubt this issue occured under high
concurrency
discussed with [~brahmareddy] offline , i think we can extend removalListener
to cacheBuilder to solve the problem
any suggestions ?
