    Description

      This bug is similar to DERBY-4419, only that it uses columns that are auto-generated from expressions and not identity columns. The proposed fix for DERBY-4419 only addresses the case with an identity column.

      ij> create table t1(x int);
      0 rows inserted/updated/deleted
      ij> create table t2(x int);
      0 rows inserted/updated/deleted
      ij> create table t3(x int, y generated always as (2*x));
      0 rows inserted/updated/deleted
      ij> insert into t3 select * from t1 union select * from t2;
      ERROR XJ001: Java exception: ': java.lang.NullPointerException'.
