      Description

      A NPE occurs at org.apache.derby.iapi.util.JBitSet.or().

      A NPE occured at the same location before: http://issues.apache.org/jira/browse/DERBY-1574
      The bug was confirmed by Bryan Pendleton to show in the HEAD as well: http://mail-archives.apache.org/mod_mbox/db-derby-user/201002.mbox/%3C4B79F74E.1000005@amberpoint.com%3E

      To reproduce:
      ----------------------

      CREATE TABLE ABC (ID int PRIMARY KEY NOT NULL);
      CREATE TABLE DEF (ID int PRIMARY KEY NOT NULL);

      SELECT *
      FROM ABC t1
      WHERE (SELECT DISTINCT t2.ID FROM DEF t2)
      IN (SELECT t3.ID FROM DEF t3)

      ----------------------

      Leads to

      error message:
      Error: DERBY SQL error: SQLCODE: -1, SQLSTATE: XJ001, SQLERRMC: java.lang.NullPointerExceptionXJ001.U
