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?
