> If the log manager is on the boot class path with Java 11, {{-Xbootclasspath/a:jboss-logmanager.jar}}, and a custom handler, formatter or filter is used the server will fail to boot as the log manager can't see the types in jboss-modules. This seems due to the fact that the log manager is on the boot class path and jboss-modules is on the system class path.
