Howdy,

That's your use-case, not mine.  Both are debug for me.  I never want
one without the other.  theValue=... is useless if I don't know what
method it's in.

No such requirement exists in any organization I've ever worked, people
use debug-level statement without extending log4j.  People who use JDK
1.4 don't use the trace level.  But that's only my experience, which is
no less or more meaningful than anyone else's.

Convince me that a majority wants it.  How come it doesn't come up more
often on the log4j user list?

>4)  It matches levels with commons-logging.  Why does it have trace?
;-)

SOLELY because JDK 1.4 has it and commons-logging was designed to map to
both log4j and commons-logging (among other logging kits).

As Paul said, this is an eternal debate, kind of like whether to include
version numbers of a release in the jar file name.
