Separate appenders for System.out and System.err feels better to me. It
"fits" better with the OO notion of extending the general case to the more
specific.

Subject: Re: ConsoleHandler? - was method names - how slow?
Chris,
This from the log4j HISTORY file:
- The FileAppender has been split into three parts: WriterAppender,
ConsoleAppender and FileAppender. ConsoleAppender takes over the
console logging functionality of FileAppender. As a result support
for stream and console printing has been deprecated in FileAppender
although it is still there for the moment.
Both ConsoleAppender and FileAppender extend WriterAppender. The
ConsoleAppender can print both to stdout and stderr although stderr is
default. Technically both stdout and stdout are console because AFAIK any
real computer console will have both streams available both on Windows and
Unix. I chose stderr to be default because the JSR47 ConsoleHandler
supports stderr only. I am starting to wonder if it isn't better to have
two appenders (handlers if you will) Console and Error, like you have in
JLog. It's a detail but that's where the devil is. Cheers, Ceki
