Embedded wildfly server does not combine with the latest logback version. ------------------------------------------------------------------------- Key: WFCORE-3431 URL: https://issues.jboss.org/browse/WFCORE-3431 Project: WildFly Core Issue Type: Bug Components: Server Reporter: Geoffrey De Smet Assignee: James Perkins Logback 1.2.3 doesn't combine with the embedded WildFly server. Older versions did. The reason might be because Logback/slf4j now uses the JDK ServiceLoader mechanism to find the logging implementation (mandetory as of java 9 in modulepaths), which uses META-INF files, which isn't that combinable with the way jboss modules was made to work in embeddable wildfly.
