      Description

      With 10.5.1.1 and newer, the following ij session fails with a NullPointerException (production jars) or an assert failure (debug jars):

      ij version 10.10
      ij> connect 'jdbc:derby:db;create=true';
      ij> create table t(x int);
      0 rows inserted/updated/deleted
      ij> insert into t values 0;
      1 row inserted/updated/deleted
      ij> create trigger tr1 after update on t values 1;
      0 rows inserted/updated/deleted
      ij> create trigger tr2 after update on t for each row update t set x = x + 1 where x < 3;
      0 rows inserted/updated/deleted
      ij> update t set x = x + 1;
      ERROR XJ001: Java exception: ': java.lang.NullPointerException'.

      It does not fail on 10.4.2.0:

      ij version 10.4
      ij> connect 'jdbc:derby:db;create=true';
      ij> create table t(x int);
      0 rows inserted/updated/deleted
      ij> insert into t values 0;
      1 row inserted/updated/deleted
      ij> create trigger tr1 after update on t values 1;
      0 rows inserted/updated/deleted
      ij> create trigger tr2 after update on t for each row update t set x = x + 1 where x < 3;
      0 rows inserted/updated/deleted
      ij> update t set x = x + 1;
      1 row inserted/updated/deleted
      ij> select * from t;
