Stefania commented on CASSANDRA-12457:
--------------------------------------

Thank you for the review! 

Committed to 2.2 as be6e6ea662b7da556a9e4ba5fd402b7451bdde10 and merged into 
3.0, 3.X and trunk.

[~dseng]: the upgrade tests that upgrade from 2.1 will still show LEAK errors 
in 2.1 logs since this patch was not delivered in 2.1; I'm not sure if there is 
a way to ignore LEAK errors in logs, but only for 2.1 nodes.
