I get an error during wildfly startup with the following message:
NoSuchFieldError: EMPTY_BYTE_ARRAY
The message also say that this error occurs in undertow deployment. Could anybody give me a hint of what is going on here and how to solve that?
Below is the beginning of the stack trace.

我遇到过同样的问题，可以这样解决它：
1.对于war：
在src/main/webapp/WEB-INF/中包含jboss-deployment-structure.xml，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
  <deployment>
     <exclusions>
        <module name="org.apache.logging.log4j.api"/>
    </exclusions>
  </deployment>
</jboss-deployment-structure>

1.对于ear：
在src/main/application/META-INF/中包含jboss-deployment-structure.xml，如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<jboss-deployment-structure>
  <sub-deployment name="mywar.war">
     <exclusions>
        <module name="org.apache.logging.log4j.api"/>
    </exclusions>
  </sub-deployment>
</jboss-deployment-structure>

您需要从您的部署中排除API模块。您的另一个选择是使用WildFly 26，其中包含2.16版本的API。

请将log4j和log4j-api更新至2.16.0版。
如果您使用的是spring-boot so，请在pom.xml中添加标记

<properties> 
    <log4j2-version>2.16.0</log4j2-version>
  </properties>

和

<dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-api</artifactId>
            <version>2.16.0</version>
        </dependency>

在pom.xml中
