Wildfly has its own code for reading {{META-INF/services}} files and, in Wildfly 8, it doesn't handle comments properly. See [WFLY-4089|https://issues.jboss.org/browse/WFLY-4089] for details. Due to the comment in Logback's {{META-INF/services/javax.servlet.ServletContainerInitializer}} file it tries to load a class named {{# See javax.servlet.ServletContainerInitializer javadocs}}. The problem has been [fixed|https://github.com/wildfly/wildfly/commit/fef57ebdc7f93fe975d9234dd86265b79d705ce2] in Wildfly 9 and later.
