Exception during Optimization

while running the BQT Query

SELECT intkey FROM BQT1.SmallA AS A WHERE convert(shortvalue, integer) = (SELECT MAX(convert(shortvalue, integer)) FROM BQT1.SmallA AS B WHERE b.intnum = a.intnum) ORDER BY intkey

I encountered

java.lang.ArrayIndexOutOfBoundsException: -1
