Hudson commented on CASSANDRA-120:
----------------------------------
Integrated in Cassandra #59 (See
[http://hudson.zones.apache.org/hudson/job/Cassandra/59/])
change Message body to byte[]. this reveals where there are problems:
everything that is using any of the send messages already needs to be doing
that or they're broken. the good ones I just unwrap; the broken ones I fixed
except for MoveMessage which doesn't even have a byte[] serializer yet, so I
left that one broken. writeResponseResolver is the specific case that caused
the bug report.
