私はGlassfish3.1.2.2、JPAプロバイダーとしてのeclipse-link、およびJavaJDK-6u31を使用しています。私のアプリケーションは、クライアントマシン上の独自のJVMで実行されているスタンドアロンのSwingクライアントを備えた3層です。JNDIルックアップおよび@RemoteインターフェースによるEJBとの通信。
私は次のオブジェクト継承構造を持っています：
私のスーパークラス「ドキュメント」：
@Entity
@Table(name = "Document")
@Inheritance(strategy=InheritanceType.TABLE_PER_CLASS)
public class Document implements IUpdateableEntity {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE)
private Long id;
@Basic(optional=false, fetch=FetchType.LAZY)
@Lob
private byte[] content;
@Transient
private transient File file;
public Document() { }
// getters and setters ...
}
...およびサブクラス「請求書」：
@Entity
@Table(name = "Dokument")
public class Invoice extends Document implements IUpdateableEntity {
private static final long serialVersionUID = 1L;
// some additional relations and attributes ...
public Invoice () { }
// getters and setters ...
}
請求書オブジェクトを永続化するためにejbファサードを呼び出しているときにこの例外が発生します（persist（）、flush（）、refresh（）を呼び出し、自動生成されたIDをクライアントに提供するためにオブジェクトをクライアントに返します）：

WARNUNG: IOP00810011: Exception from readValue on ValueHandler in CDRInputStream

この例ではCORBAマーシャリングが明らかに失敗するため、私はすでにインターネットを調べて、serialVersionUIDの問題を示すヒントを見つけました。
次に、Netbeans IDEでデバッガーをオンにし、サーバー側のejbBeanに送信される前にオブジェクトの状態をイントロスペクトしました。
デバッガウィンドウで[静的フィールド]ノードを開くと、serialVersionUIDが重複していることに気付きました（次の画像と比較してください）。
-誰かがこの問題を解決する方法の手がかりはありますか？
私のプロジェクトには、（@ Lobなしで）非常によく似た構造のこのような他の継承構造がありますが、この問題はありません... @Lobフィールドでこの動作が発生する可能性はありますか？
助けていただければ幸いです。よろしくお願いします。
編集：これが完全なスタックトレースです：
