英文:
Wildfly 20 Upgrade and OpenJRE 8 - Implementation of JAXB-API has not been found on module path or classpath
问题
我们正在使用 openjre-8.0.252.09-hotspot，从 Wildfly 10 升级到 Wildfly 20，在此过程中遇到了以下问题，尽管：
- jaxb-impl-2.1.13.jar 已经存在于 WEB-INF\lib 中
- rt.jar（在 openjre 中）包含：com.sun.xml.internal.bind.v2.ContextFactory
我尝试了以下操作，但并未成功：
- 将 jaxb-api-2.1.jar 添加到 lib 中。
- 使用 openjdk 替代 openjre。
为什么应用程序无法找到已经存在于 rt.jar 中的 com.sun.xml.internal.bind.v2.ContextFactory 类？
还有其他我遗漏的内容吗？
我尝试过搜索，但所有答案都与 Java 9 及以上版本有关，而与 openjre-8 无关。
错误信息：
Caused by: javax.xml.bind.JAXBException: 在模块路径或类路径上找不到 JAXB-API 的实现。

We are using openjre-8.0.252.09-hotspot, upgraded from Wildfly 10 to Wildfly 20, and started facing following issue, although:
- jaxb-impl-2.1.13.jar is already present in WEB-INF\lib
- rt.jar (in openjre) has: com.sun.xml.internal.bind.v2.ContextFactory
I have tried adding the following which did not work:
- jaxb-api-2.1.jar to the lib.
- used openjdk instead of openjre
Why is the application not able to find the com.sun.xml.internal.bind.v2.ContextFactory class which is already present in rt.jar ?
Is there something else that I am missing ?
I tried searching, but all the answers are related to java 9 and above, but no answers fro openjre-8.

RootCause:
应用程序的WebInf/lib中有一个jar文件，其中的jaxb.properties文件包含以下条目：
javax.xml.bind.context.factory=com.sun.xml.internal.bind.v2.ContextFactory
删除此条目解决了此问题。
英文:
RootCause:
One of the jar in application's WebInf/lib had jaxb.properties which had following entry:
javax.xml.bind.context.factory=com.sun.xml.internal.bind.v2.ContextFactory
Removing this resolved the issue.
