------------------------------------------------------------------------

Thanks Taras for commenting on the issue, I just ran into the same problem with a super column
family with a TimeUUIDType comparator, and UTF8Type subcomparators; I can insert, get data
all day long from the cluster while it is running fresh. But the moment I restart the cassandra
node, I get the exception saying that TimeUUIDTypes must be exactly 16 bytes.

Edit: Just verified your fix and it fixes my case as well.

> It seems this has something to do with indexes, and I do have a CF with an index on it,
but it is not used.
> I can try and remove the index with 0.7.x binaries, but I will wait a bit to see if anyone
needs it to reproduce the bug.
