One thing which would be nice is, to provide an actual message in the assertion
in order to avoid this "null" string. Furthermore it would be great to provide
the data which caused the assertion to fail.
Actually I have no clue, how we triggered this, but I will see if I can find
out something...
The only similiar Issue I found in the tracker was CASSANDRA-11074.
