本番環境の appengine インスタンスのサーバー ログにこの例外がスローされます。org.codehaus.jackson.jaxrsパッケージ内のいくつかのクラスからメンバーをロードできないことに関する SecurityExceptionです。誰もこれを見たことがありますか？Jersey 1.12、MimePull 1.6、および Urlrewrite 3.2.0 ライブラリを追加しました。
これらの例外は主にログを埋めますが、アプリケーションの品質には影響しないようです。これらはデバッグ用の Jetty サーバーには表示されません。
これらの他のクラスでも同様のエラーが発生します。
- JacksonJaxbJsonProvider
- JacksonJsonProvider
- JSONWithPaddingProvider
