Sylvain Lebresne commented on CASSANDRA-9857:
---------------------------------------------
So, as pointed by [~bdeggleston] in CASSANDRA-9893, the backward compatibility
tests from CASSANDRA-9704 does allow to expose this problem. So I've pushed a
branch [here|https://github.com/pcmanus/cassandra/commits/9857] with a fix for
this (which turns out not too hard). I've validated locally that this was
fixing the {{large_count_test}} from Tyler's CASSANDRA-9704 tests in particular.
As a side note, on CASSANDRA-9893, Blake attributes the failure of
{{static_columns_with_distinct_test}} to this, but I don't think that it's the
case. I'm investigating what the real cause is and will followup on
CASSANDRA-9393 but in any case, the patch here does fix the legitimate bug this
ticket is about.

> This ticket is related to CASSANDRA-9856 and CASSANDRA-9775. Even if the
> broken/incomplete serialization of {{AbstractBounds}} is not a problem per-se
> for pre-3.0 versions, it's still a problem for trunk and even though it's
> fixed by CASSANDRA-9775 for 3.0 nodes, it might be a problem for 3.0 nodes
> talking to older nodes.
> As the paging tests where those that exposed the problem (on trunk) in the
> first place, it would be nice to modify said paging tests to work on mixed
> version clustering so we can valid if it is a problem. If it is, then we'll
> probably have to add redundant checks on trunk so they ignore anything the
> 3.0 node sends incorrectly.
