That is correct, and in fact I've double up every debugging method - there is a log(Object) and log(Object...) method for each level. This mitigates that issue slightly, and I would argue that the cost of creating short-lived object arrays is still much less than string concatenation, especially with modern JVM's. It's a trade-off of efficiency vs. flexibility.
