隨着IBM JDK8看到sun.io.UnknownCharacterException異常

Question

當我開始我們的產品時，我遇到了這個異常。如果我將JDK切換到JDK7，則啓動正常。

可能是類似這樣的，但我看到了這個問題，所有的數據庫： Connect to DB2 database in eclipse via jdbc

Answer 1

的IO代碼頁（字符集）從刪除IBM JDK 8.爲了解決問題，您必須在應用程序中使用NIO字符集。另外，請確保在應用程序中使用標準Java API（請注意，不建議在應用程序中使用像sun.io. *這樣的實現類，因爲它可以隨時在沒有任何事先通知的情況下進行修改/刪除）。
