類GsonMessageBodyHandler是實現MessageBodyReader<T>一個抽象類，它有沒有註釋。然後，這個方法被一個名爲JsonMessageBodyHandler的類所分類。 JsonMessageBodyHandler註明@Producer和@Consumes(MediaType.APPLICATION_JSON)。球衣的錯誤，試圖實例抽象類
當我部署我的項目是非模糊的，它工作正常。然而，當我模糊，即使我告訴ProGuard的不混淆GsonMessageBodyHandler和JsonMessageBodyHandler，新澤西出於某種原因堅持嘗試實例GsonMessageBodyHandler作爲一個供應商，然後失敗，因爲它是抽象的。我無法確定是什麼導致澤西試圖加載這個抽象類，但只有在混淆後才能加載。誰能幫忙？
球衣版本是1.17。

感謝您的答覆，我做了檢查是一定的，並在ProGuard配置文件有： -keepattributes例外，InnerClasses，簽名，不推薦使用，的SourceFile，LineNumberTable，*註釋*，合成，EnclosingMethod。無論如何，即使它剝離了註釋，抽象基類仍然沒有註釋。出於某種原因，澤西正試圖實例化抽象類。 – user2352817 2013-05-10 03:42:14
