Sylvain Lebresne resolved CASSANDRA-9705.
-----------------------------------------
    Resolution: Fixed

Yes, there were a few small problems with reading old sstables. I should have 
run those tests but I forgot sorry. Anyway, took the liberty to directly fix 
those in commit 
[f713be4a|https://git1-us-west.apache.org/repos/asf?p=cassandra.git;a=commitdiff;h=f713be4a],
 so closing again (if you still find upgrade tests that are broken, feel free 
to re-open, but in that case please point me to which test is failing exactly 
cause the upgrade tests I've used are all passing).

> Simplify some of 8099's concrete implementations

> As mentioned in the ticket comments, some of the concrete implementations 
> (for Cell, Row, Clustering, PartitionUpdate, ...) of the initial patch for 
> CASSANDRA-8099 are more complex than they should be (the use of flyweight is 
> typically probably ill-fitted), which probably has performance consequence. 
> This ticket is to track the refactoring/simplifying those implementation 
> (mainly by removing the use of flyweights and simplifying accordingly).
