I'm keeping my eye open! :-)
We went several rounds on this issue. If I recall, Graham's notion of a
console to which messages should go was stderr. I couldn't convince him
otherwise.
In retrospect, what I should have done (and still can) is to create a
PrintStreamHandler and extended ConsoleHandler and ErrorHandler from that.

Subject: ConsoleHandler? - was method names - how slow?
Hi Chris,
Good to have you around! One unrelated question. JSR47 has a ConsoleHandler
that logs to System.err. JLog has a ConsoleHandler that logs to System.out
and ErrorHandler that logs to System.out. Do you know why Graham chose to
have ConsoleHandler log only to System.err? Your model seems to make more
sense... Just curious. Ceki
