> Found this while working on DERBY-4397 for a similar case with ORDER BY inside an IN-subquery:
> Repro:
> create table t(i int not null, constraint c unique (i), j int, k int);
> insert into t values (1,10,1),(2,40,1),(3,45,1),(4,46,1),(5,90,1);
> select sum(j) from t group by i having i in (select i from t group by i,j );
> gives NPE:
> ERROR XJ001: Java exception: ': java.lang.NullPointerException'.
> java.sql.SQLException: Java exception: ': java.lang.NullPointerException'.
