Log4jLogger was removed in
CXF-8264, but LogUtils is still trying to instantiate it when SLF4J has a binding for Log4J or JCL->Log4J.
As a result, when both slf4j and log4j-slf4j-impl are in the classpath, CXF still sends logs to JUL.
LogUtils should always use Slf4jLogger instead.
I will submit a PR on GitHub to fix this.
