The Lumberjack project provides an open source (covered
by the
GNU Lesser Public
License) implementation of the logging APIs first introduced in JDK
1.4 that will work for JDK 1.2 and 1.3. The goal is for this implementation
to work transparently on JDK 1.2 and 1.3 without recompile and with no
significant difference in behavior between it and the implementation provided
in JDK 1.4 (differences will be ruthlessly eradicated when found :-). More
information about the logging API can be found in JSR
47, the
logging
page in the
documentation
for JDK 1.4, the
overview
of Logging, and the
javadoc
for java.util.logging.
The intent is to allow developers to gain experience
with the logging API sooner so that they can become more familiar with
the API before moving to 1.4, and to allow them to write code that will
move without change to 1.4. This should speed adoption of the logging APIs
and build a collection of custom filters and handlers more quickly.

The latest release (0.9.3) of Lumberjack was made available on January 13th, 2002. It fixes a number of bugs in the implementation.
While Lumberjack can't become final until JDK 1.4 becomes final (currently
estimated at 4Q2001), the implementation is essentially complete at this point
and there is little implementation work left to be done. From here forward,
changes will be primarily bug fixes or adjustment to changes in the
specification.
Lumberjack was implemented from scratch (clean room
from any Sun materials except JSR 47) by Brian
R. Gilstrap. Hopefully, others will find it worthwhile and join
in making it better.
