------------------------------------------------------------------------
I was not able to reproduce this. 3 nodes, ByteOrderedPartitioner, I created a
keyspace with SimpleStrategy, RF3, one table, inserted some data, flushed,
called nodetool status 100x in a loop. No error.
I tested 3.0.28, 3.11.14 as well as trunk (4.2-SNAPSHOT).

> I often encounter a ClassCastException when trying to run `nodetool status`

> error: null

> java.lang.ClassCastException
> {noformat}
> A couple of times, I've gotten lucky and nodetool has provided a more verbose

> There are 3 nodes in the cluster, and it's using the SimpleStrategy with a 3x
> replication factor. It's using the ByteOrderedPartitioner (which I know is
> frowned upon).
