ConsoleAppender and System.{out,err}.println
I'm maintaining a Java app with tons of System.out.println's all around,
and I'm using log4j in my (new) code.
If I setup log4j to use a ConsoleAppender, will log4j's and println's
output be intermixed in a predictible way? I mean, will each log message
be logged until EOL at least?
Does anyone have any suggestions for using System.out.println and log4j
together in the same app?
Thanks in advance

There's also option of using LoggingOutputStream (in contribs in CVS) which
redirects System.out/.err to log4j. Handy.

If want to distinguish log4j msgs form u'r
system.out's then you can use some pattern with
timestamp or className.method.
This way there will be a difference. Also, since log4j
has levels, you may be able to distinguish based on
it.

AFAIK, System.out.println is synchronized.
