Description

nodetool cfhistograms raises an AssertionError on the CassCI trunk jobs:

http://cassci.datastax.com/job/trunk_dtest/lastCompletedBuild/testReport/jmx_test/TestJMX/cfhistograms_test/history/

This regression started in this build on CassCI and has failed consistently since then:

http://cassci.datastax.com/job/trunk_dtest/806/testReport/junit/jmx_test/TestJMX/cfhistograms_test/

I can't find any recent dtest changes to this method, so I believe it's a Cassandra bug. Here's the changeset for the first failing build:

Maybe something in the changes to the scripts here introduced the bug:

https://github.com/apache/cassandra/commit/b5240204d7aa2a32c6649d19da2b961c856cde28

jjordan could you have a look at this please?

This appears to only affect trunk at present.
