> 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.
