>          Components: Core

>         Environment: 1 node cluster running on branch cassandra-1.0. Ubuntu. both key
and row caching were enabled.

> Enabled row and key caching. Used stress to insert some data. ran nodetool flush, then
nodetool compact. Then read the data back to populate the cache. Turned row_cache_save_period
and key_cache_save_period really low to force saving the cache data. I verified that the row
and key cache files existed in /var/lib/cassandra/saved_caches/.
> I then killed cassandra, checked out branch cassandra-1.1, compiled and tried to start
the node. The node failed to start, and I got this error:
