    Description

      ij> create table t(x int);
      0 rows inserted/updated/deleted
      ij> select t1., t2. from t t1 join t t2 using ;
      ERROR XJ001: Java exception: ': java.lang.NullPointerException'.

      This statement should have raised an exception because both t1.* and t2.* expand to no columns. See DERBY-4407.
