Sweet - I did not realize that. Let's just go with SLF4J!

The time it takes to create objects in Java is negligible compared

they are rarely used consistently. Slf4j supports logging messages

format and array of objects as parameters,

Without arguing either side, just be aware that with varargs, some

compiler turns the above into:
log.debug( "User with ID {0} logged into realm {1}", new Object[
]{userId, realm});
which creates a new Object[ ] (that is garbage collected
immediately), so
it's still not "free", even if it is less expensive than String
concatenation.

Thanks Craig - hadn't thought about that. Even if there is still a
small
performance penalty (the Object[] creation), it does significantly
clean up
the code. I'm not strongly opinionated for or against it. But I'd
be more
open to a custom logging wrapper that offers some value-adds like
this vs.
one that is simply just another wrapper layer.
