<sigh/> I'm a nitwit. I got confused because at my last job we used a wrapper around slf4j, and the signature of the method was debug(String, Object...). Out of curiosity, is there a reason why that format wasn't used? The compiler should be smart enough to call the more specific debug(String, Object, Object) when appropriate. Changing from Object[] to Object... should also be backwards-compatible... Thanks, Marco!

I'm running in Eclipse Indigo, and my classpath looks like this: logback-classic-1.0.0.jar logback-core-1.0.0.jar slf4j-api-1.6.4.jar Does anybody know why the compiler is using the wrong method?
