ResultSet が閉じているかどうかを確認しているときにエラーが発生しました。これは、netbeans 7.3 で発生した実際のエラーです。

スレッド「AWT-EventQueue-0」での例外 java.lang.UnsupportedOperationException: Sun.jdbc.odbc.JdbcOdbcResultSet.isClosed(JdbcOdbcResultSet.java:6753) でまだサポートされていない操作

エラーが発生したコードは次のとおりです。

try{
    if(!rs.isClosed());
    rs.close();
}catch(SQLException ex){
    JOptionPane.showMessageDialog(rootpane, ex);
}

ご協力ありがとうございます。
