java - アプリケーションでの複数の JVM の問題

Question

お客様のマシンでの Java への依存を避けるために、アプリケーション Jar と JRE もパックしているデスクトップ アプリケーションがあります。

ただし、問題は、顧客がすでに Machine に Java をインストールしている場合です。一部のクラスの Java バージョンの依存関係が原因で、クラス定義の例外がないなどの問題に直面しています。

ここで私の質問は、アプリケーションがパッケージ化された JRE を常に使用してアプリケーションを起動し、インストールされている場合はシステム JRE を使用しないようにする方法です。
