我在部署在 WebLogic 12c 上的应用程序中从 guava 14.0.1 更新到 15.0,并且在部署期间我得到了一个我无法解决的 java.lang.NoSuchMethodException:

我已经在我的 weblogic.xml 文件中使用 WebLogic prefer-application-packages 类加载器过滤,如此处所述,以解决 WebLogic 12c 中的运行时冲突,因为它似乎重新打包了旧版本的库。这一直在 guava 14.0.1 中工作,但在 15.0 中没有。
据我所知,首选 com.google.common.* 包应该包含所有内容。这个 Finalizer 类是否在类加载器过滤发生之前做了一些特殊的事情,从而试图加载似乎具有不同 API 的旧版本?
是否有替代解决方案使用与应用程序一起打包的 guava-15.0.jar 而不是与服务器捆绑的内容?
