7.12 と 8.0 で奇妙なエラーが発生しました。1 つのオブジェクトを双方向に複製しようとしています。どちらも db4o データベースであり、クライアントは埋め込みを介してローカル データベースに接続し、db4o サーバーに接続してレプリケーションを開始します。

システムは Mac OS X 10.7.3、Java バージョン:

java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b04-415-11M3635)
Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01-415, mixed mode)

サーバー上のエラーは次のとおりです。

objc[7665]: Object 0x7ff03c0020e0 of class __NSArrayM autoreleased with no pool in place
- just leaking - break on objc_autoreleaseNoPool() to debug

クライアントのエラーは次のとおりです。

私は数日間それを機能させようとしてきましたが、あまりうまくいきませんでした。

例外は配列に関連しているようですが、オブジェクトで配列のようなものを使用していません。ただし、これは内部の db4o 構造である可能性があります。

とにかく、すべての助けに感謝します！

うーん、2 番目のスタック トレースにレプリケーション スタック フレームが表示されず、ネイティブ クエリのみが表示されます。

メッセージ「objc[7665]: クラス __NSArrayM のオブジェクト 0x7ff03c0020e0 は、プールが配置されていない状態で自動解放されました - ただリークしています - objc_autoreleaseNoPool() で中断してデバッグしてください」

私には非常に疑わしく見えます。db4o が MacOS 内部のもので UI オブジェクトを保存またはシリアライズしようとしているように。通常の Java オブジェクトが __NSArray と参照カウントを使用しているとは思えません。

このことから、サーバーに対してネイティブ クエリを実行していると推測できます。そのクエリはSODAに変換できませんでした。その場合、db4o は query-object をシリアライズしてサーバーに送信しようとします。クエリはおそらく内部クラスであり、GUI オブジェクトを含む外部コンテキストを参照します。そして、それがこの問題を引き起こします。

私の推奨事項: サーバーに対するクエリには SODA クエリのみを使用してください。ネイティブ クエリは、クライアント サーバー モードで多くの問題を抱えています。この問題の原因となるクエリを SODA クエリに変更し、問題が解決するかどうかを確認します。
