This was seen in CASSANDRA-6738 (Not Reproduced), CASSANDRA-7112 (Fixed 2.1
rc1) and CASSANDRA-7990 (Fixed 2.1.1). I decided to open a new Jira since this
is being observed in a version where it should have been fixed and wasn't sure
if perhaps one of the other Jiras should be reopened instead so I'll leave it
to the experts.
Since the sstables are sensitive, I can share the data privately as needed to
reproduce and diagnose the issue.
