Duplicate Proxy.newProxyInstance calls during PGXAConnection.getConnection?

  @Override  public Connection getConnection() throws SQLException {

    // the first time ConnectionHandler has been created.    Connection conn = super.getConnection();   
    // When we're outside an XA transaction, autocommit    // is supposed to be true, per usual JDBC convention.    // When an XA transaction is in progress, it should be    // false.    if (state == State.IDLE) {      conn.setAutoCommit(true);    }
    /*     * Wrap the connection in a proxy to forbid application from fiddling with transaction state     * directly during an XA transaction     */

    // ConnectionHandler is created again here.     ConnectionHandler handler = new ConnectionHandler(conn);    return (Connection) Proxy.newProxyInstance(getClass().getClassLoader(),        new Class[]{Connection.class, PGConnection.class}, handler);  }
