Clustered Wildfly抛出java.lang.IllegalAccessError

2024年1月27日 189次阅读

我在Wildfly托管域上运行应用程序,该域由2个虚拟机组成,每个VM上有3个服务器.

console.log中发生异常：

我试图在wildfly 8.2.1.Final和9.0.2 Final上使用openjdk-1.8和Oracle jdk-1.8运行应用程序,结果相同.应用程序已部署并运行且没有错误,我通过负载均衡器(循环法)成功登录并在服务器上工作.

In undertow sources at github字段hashCode类io.undertow.util.HttpString声明为最终瞬态int.为什么readObject方法试图以非常奇怪的方式改变这个字段的值？

我用谷歌搜索了互联网,但没有发现这个或类似的错误,也不知道如何处理它.

在我的申请中哪个地方属于这个例子？

更新：
这个Undertow server补丁帮我避免了问题：

最佳答案 这已在Wildfly中修复,见
fix.
