我正在将 Web 应用程序（war 文件）部署到 JBoss 7.4 服务器环境。

JBoss EAP 7.4.0.GA (WildFly Core 15.0.2.Final-redhat-00001) starting

Java版

 java.home = /usr/lib/jvm/java-11-openjdk-11.0.14.0.9-1.el7_9.x86_64

此 Web 应用程序使用 Mojarra 2.3.14 + Richfaces 4.5.4 + Openfaces 3.0 库用于一些 UI 屏幕。

该应用程序在 JBoss 7.1/Java 8 上运行良好。升级到 JBoss 7.4/Java 11 后，UI 屏幕上的任何 Ajax 调用都会在服务器日志文件中给出以下错误。JSF 相关库没有变化。

以下错误来自 Openfaces 3.0 库。

这个相同的 Web 应用程序在 JBoss 7.1 和 Java 8 上没有问题。有人知道为什么我们会遇到错误吗？
