I would like to upgrade the Wildfly version I'm using for my Spring boot projects. This to go from "wildfly-21.0.2.Final" to "wildfly-24.0.1.Final". But, if I don't add the following exclusion to all the spring boot dependencies :
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
</exclusion>
I end up with the following RuntimeException :
[0m[31m18:13:11,977 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 86) MSC000001: Failed to start service jboss.deployment.unit."en74-t2-0.0.1-SNAPSHOT.war".undertow-deployment: org.jboss.msc.service.StartException in service jboss.deployment.unit."en74-t2-0.0.1-SNAPSHOT.war".undertow-deployment: java.lang.RuntimeException: java.lang.IllegalArgumentException: LoggerFactory is not a Logback LoggerContext but Logback is on the classpath.

I have found the solution of the exclusion with the answers of the following question :
LoggerFactory is not a Logback LoggerContext but Logback is on the classpath
But this solution stops Spring boot writting in the logs all together. This doesn't help if you want to see the errors displayed by Spring boot or if you want to put some information in the logs.
The problem can be better understood with the 6 files in this repository :
https://github.com/aiHFL/for-stackoverflow-question-num-01.git
Is there another way to change the pom.xml file or other so that we don't have this RuntimeException ?
