      Looking at the code ..

      the call
      removeMarkedReferences(c, null, "T");

      the method
      protected void removeMarkedReferences(Connection c, Tx txid, String mark) throws SQLException
      {
      PreparedStatement stmt = null;
      try
      {
      stmt = c.prepareStatement(DELETE_MARKED_REFERENCES);
      stmt.setLong(1, txid.longValue());
      stmt.setString(2, mark);
      stmt.executeUpdate();
      }


      I'm assuming that the NPE is that txid is null?
