Sylvain Lebresne resolved CASSANDRA-10626.
------------------------------------------
Resolution: Duplicate
Almost surely a duplicate of CASSANDRA-10579 (not the same error that in that
ticket description but that's because the user had assertions disabled and if
you look in the comment he gets the same stack with assertion enabled). If you
can test the patch there and if it doesn't solve your problem, feel free to
reopen however.
