I just got a similar-looking NPE stack trace. The node that raised the
exception was receiving streams from a node being decommissioned (with
"nodetool decommission"). Both nodes were running 0.8.6; both had been
upgraded a few hours earlier from 0.8.4.
The first:

> Components: Core
> Affects Versions: 0.8.1
> Reporter: Héctor Izquierdo
>
> A NPE is generated during repair when closing an sstable generated via
> SSTable build. It doesn't happen always. The node had been scrubbed and
> compacted before calling repair.
