I'm seeing a funny error when trying to write to logback. import org.slf4j.Logger; import org.slf4j.LoggerFactory; final String arg1 = "arg1"; final String arg2 = "arg2"; final String arg3 = "arg3"; LOGGER.debug("Hi {} {}", arg1, arg2); LOGGER.debug("Hi {} {} {}", new String[] { arg1, arg2, arg3 }); LOGGER.debug("Hi {} {} {}", arg1, arg2, arg3); The last line is giving this error message: The method debug(Marker, String, Object, Object) in the type Logger is not applicable for the arguments (String, String, String, String) I don't see why it isn't using the method whose signature is debug(String, Object[]), especially given that I'm not using a Marker. 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?
