Spring Boot: 2.4.2 JDK: AdoptOpenJdk 1.8.0_275
Expected behavior: Excluding tomcat from starter web and including undertow, should start web server without any issue.
Found behaviour: Excluding tomcat from starter web and including undertow, throws class not found org.jboss.logging.Logger.
Additional Notes: Switching to Jetty is working without issue. Adding org.jboss.logging:jboss-logging does not help.
Comment From: wilkinsona
org.jboss.logging:jboss-logging is a transitive dependency of io.undertow:undertow-core and should be on the classpath automatically without explicitly declaring a dependency on it. If org.jboss.logging.Logger isn't on the classpath, it sounds like the jboss-logging jar file was corrupted when your build system downloaded it. Try clearing it from your build system's cache and rebuilding your application.
