xsd ファイルから JAXB によって生成されたクラスに、クラスのリストも含む一連のクラスのリストがある場合がいくつかあります。生成されたクラスは、これらのケースを処理するときに静的な内部クラスを使用しますが、これにより、クラスが複数回存在する複数のインスタンスが発生します。
例として、複数の xsd ファイルに存在する Parameter クラスがあります。すべてのインスタンスで、このパラメータ クラスは同じで、キーと値のペアが含まれています。これらの xsd ファイルごとにコードを生成すると、生成された各クラスには Parameter という名前の内部クラスが含まれます。
冗長性を減らすために、生成されたすべてのクラスから Parameter クラスを削除し、再実装して、すべての参照を更新しました。これは期待どおりに機能します
複数のクラスで実装されている LogicalDevice などの別のクラスがあると、問題が発生します。LogicalDevice には ParameterList が含まれています。LogicalDevice が独自のクラスに抽出され、参照が更新されると、Parameter クラスの最初の属性のみが保持され、残りは null になります。
このことから、静的内部クラスには何か特別なものがあると思われます。
参考までに、ここに私のxmlとコードがあります

何が起こっているかを繰り返します。Policy 静的クラス内に含まれるパラメーター データは期待どおりにありますが、LogicalDevice の下のパラメーター データにはキーのみが含まれ、値データはすべて null に設定されます。
これらの変更でデータが失われる理由、または静的クラスが必要な理由を知っている人はいますか?
