> Both the Java client and C++ client/server currently have a bug where
> attempting a scan with an {{IS NOT NULL}} predicate on a primary key column
> can throw an exception (Java), or crash the C++ client or server. This is a
> rare situation currently since {{IS NOT NULL}} is not publicly accessible, so
> it has to come from a simplified predicate like {{my_int8_column <= 127}}.
> The fix is straightforward: stop encoding the lower/upper bound keys when an
> {{IS NOT NULL}} predicate is encountered.
