The GWTBridge has been moved to com.google.gwt.core.shared.GWTBridge

In the "Impl" class the method create of the GWT class is used and this redirects with a step in between to the GWTBridge of the shared package. Are you sure your dependencies are correct?
I'm using slf4gwt with 2.10 since it came out without seeing this issue.

So the server is using the org.slf4j.LoggerFactory class inside slf4gwt not the one in slf4j-api is this expected ?
Does gwt in org.gwtproject makes any difference compared to com.google gwt ?

Running the app using appengine or jetty gives the same result
