We will have to modify log4j-slf4j-impl to support the new binding mechanism. I 
know it uses service loader but I haven’t looked at the details. I looked at 
service loader when I created the binding between our api and core but decided 
not to use it because I wanted to also include the logic to match API versions. 
So what we have is something similar to service loader but it doesn’t use it.
