Clustered Wildfly 抛出 java.lang.IllegalAccessError
Clustered Wildfly throws java.lang.IllegalAccessError
我在 Wildfly 托管域上 运行ning 应用程序，该域由 2 个虚拟机组成，每个 VM 上有 3 个服务器。
异常发生在console.log:

我正在尝试 运行 在 wildfly 8.2.1.Final 和 9.0.2 Final 上使用 openjdk-1.8 和 Oracle jdk-1.8 应用程序结果。应用程序已部署并且 运行 没有错误，我已成功登录并通过负载平衡器（循环法）在服务器上工作。
In undertow sources at github class io.undertow.util.HttpString 的字段 hashCode 声明为 final transient int。为什么 readObject 方法试图以非常奇怪的方式更改此字段的值？
我在 Internet 上进行了搜索，但没有发现任何关于此错误或类似错误的信息，也不知道该如何处理。
在我的应用程序中，属于此异常的地方可能在哪里？
更新：
Undertow server 的这个补丁帮助我避免了问题：
