Mule 4.9使用Log4j JMS Appender对接ActiveMQ时的javax与jakarta JMS包冲突问题求助

我刚接触Mule，最近在尝试用Log4j的JMS Appender把日志推送到ActiveMQ队列，过程中碰到了包依赖的棘手问题，想请大家帮忙看看！

之前在Mule 4.3的情况 #

一开始在Mule 4.3版本配置JMS Appender时，直接报了错误：

2025-06-05T07:02:25.588889200Z WrapperListener_start_runner ERROR Could not create plugin of type class org.apache.logging.log4j.core.appender.mom.JmsAppender for element JMS: java.lang.NoClassDefFoundError: javax/jms/JMSException

at org.apache.logging.log4j.core@2.24.2/org.apache.logging.log4j.core.config.plugins.util.PluginBuilder.build(PluginBuilder.java:140)

查了资料后找到了解决方法：把javax.jms-api.2.0.1.jar放到mule/lib/boot目录下，错误就消失了，功能也正常跑起来了。

升级到Mule 4.9后的新问题 #

结果最近把Mule版本升级到4.9之后，新的问题又来了，启动时报错：

WrapperManager: Initializing...
Running Mule in testing mode
java.lang.module.ResolutionException: Modules javax.jms.api and jakarta.jms.api export package javax.jms to module org.apache.maven.resolver.transport.wagon
at java.base/java.lang.module.Resolver.resolveFail(Resolver.java:901)
at java.base/java.lang.module.Resolver.failTwoSuppliers(Resolver.java:815)
at java.base/java.lang.module.Resolver.checkExportSuppliers(Resolver.java:736)

我自己分析了下，应该是javax.jms和jakarta.jms的包都导出了同一个javax.jms包，导致模块系统冲突。但奇怪的是，我自己的项目pom.xml里并没有引入jakarta.jms的依赖，会不会是Mule 4.9的runtime自动包含了这个依赖？

现在陷入了两难：

• 如果删掉mule/lib/boot下的javax.jms-api.2.0.1.jar，就会回到最初的NoClassDefFoundError
• 但保留这个jar，就会触发上面的模块冲突错误

附上我当前项目的pom.xml配置：

有没有朋友碰到过类似的问题？或者知道怎么解决Mule 4.9下Log4j JMS Appender和ActiveMQ的依赖冲突问题？
