One thing I want out of log4j2 is the ability to do pass small-in-number message parameters without paying the expense of constructing an object array. I was a bit surprised not to see trace/debug/info/warn/fatal methods that would accept 1, 2, and 3 message parameters. I think only after there are 3 do you want to use varargs. This should cover more than 90% of the common developer cases.
Thoughts? Cheers, Paul
