I am currently migrating from Wildfly 18 to 33, passing through version 26. I noticed that upon switching to 26, my application logs stopped appearing.
I made the following changes in my pom.xml:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
    <exclusions>
        <exclusion>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
        </exclusion>
    </exclusions>
</dependency>

I added the logback exclusion because I encountered this error:

LoggerFactory is not a Logback LoggerContext but Logback is on the classpath. 
Either remove Logback or the competing implementation (class org.slf4j.impl.Slf4jLoggerFactory loaded from jar:file:/../wildfly-33.0.0.Final/modules/system/layers/base/org/slf4j/impl/main/slf4j-jboss-logmanager-2.0.1.Final.jar!/). 
If you are using WebLogic you will need to add 'org.slf4j' to prefer-application-packages in WEB-INF/weblogic.xml: org.slf4j.impl.Slf4jLoggerFactory

Despite this error, the logs appear.

I am using org.jboss.logging.Logger for logging.

Has anyone encountered this problem before? Do you have any suggestions?

Thanks in advance!

I accessed the console, where I had to reconfigure the standalone settings after the migration by removing ‘default-migration’ because I couldn’t connect anymore. I then removed and re-added the root-logger configuration. When I do this, the server displays my application logs again. However, upon restarting the server, the logs disappear.
