[logback-user] Throwable with Java 1.6 Style?

Why is there no way to do something like... logger.error("blah blah {} blah", exception, object); It seems that the only way to pass that in to the logger is to use if (logger.isErrorEnabled()) logger.error("blah blah " + object.toString() + " blah", e); or am I mistaken? It seems that this would be a useful function to make available. -Eric
