> Dag H. Wanvik identified this problematic query in DERBY-4342:
> ij> create table t(x int, y int);
> 0 rows inserted/updated/deleted
> ij> insert into t values (1,2);
> 1 row inserted/updated/deleted
> ij> select * from t t1 right join t t2 on t1.x=t2.x where coalesce(t1.x,t1.y) = 1;
> ERROR 38000: The exception 'java.lang.ArrayIndexOutOfBoundsException: -1' was thrown while evaluating an expression.
> ERROR XJ001: Java exception: '-1: java.lang.ArrayIndexOutOfBoundsException'.
> With a debug build, an assert failure is raised instead:
> ij> select * from t t1 right join t t2 on t1.x=t2.x where coalesce(t1.x,t1.y) = 1;
> ERROR XJ001: Java exception: 'ASSERT FAILED sourceResultSetNumber expected to be >= 0 for T1.X: org.apache.derby.shared.common.sanity.AssertFailure'.
