Do you remember why we need slf4j dependency in cxf-rt-features-logging ? Is it because it needs support MDC in https://github.com/apache/cxf/blob/master/rt/features/logging/src/main/java/org/apache/cxf/ext/logging/slf4j/Slf4jEventSender.java ? Can the slf4j logger be replaced with cxf's LogUtils.getLogger and it won't include a slf4j dependency if user uses jdk logging?
Thanks, Jim
