You can still skip over the method of the bridge, but usually it only works if you know all the bridges that can happen because this code tend to be depend on the implementation of each bridge, 
practically, there is less than half a dozen of logging libraries used in Java, so it's doable. 

The other solution is to ask every maintainers of the logging libraries to implement the System.Logger API introduced in 9.
