Minor Description
The current CXF Slf4jLogger just invokes the internal slf4j logger object.
In this way, it cannot show the original logging location.
For example, when logging configuration contains something like '%C:%L', it
prints the Slf4jLogger class name and its line number instead of the caller's class name and its line number.
In order to show the original logging locations nicely, we can use LocationAwareLogger#log(, fqcn, ...) operation. With provision of the FQCN of the wrapper class, the underlying slf4j logger will find the exact logging location.
I'll provide a patch for this in this issue.
