From the Jira,

> One possibility is that getToken of OPP can return hex value if itfails to encode bytes to UTF-8 instead of throwing error. By this systemtables seem to be working fine with OPP.


This looks like an option to try for me.

Thanks!

    Hi,

    I know it has been depreciated, but OrderPreservingPartitioner
    still works with 1.2?

    Just wanted to know how it works, but I got a couple of exceptions
    as below:

    ERROR [GossipStage:2] 2013-08-23 07:03:57,171 CassandraDaemon.java
    (line 175) Exception in thread Thread[GossipStage:2,5,main]

    I tried to setup 3 nodes cluster with tokens, A, H, P for each.
    This error was raised by the second node with the token, H.

    Thanks,
