MessageServiceFactory is an abstract class so it is not the class returned. If you don't get an exception then it must be loading the class declared in META-INF\services\org.apache.james.mime4j.dom.MessageServiceFactory that is org.apache.james.mime4j.message.MessageServiceFactoryImpl BTW, can you provide a failing test case for your scenario? If not, then maybe you have something weird in your classpath (e.g: multiple mime4j versions).
