This thread local functionality can usually be built up very easily:
you need a custom formatter of some sort for the logging messages (all
logging frameworks allow this kind of stuff AFAIK), and a few calls to
set the thread local fields. There's no need to implement a whole
logging framework ;)

In JBoss, the reliability problems are hidden thanks to the
classloading strategy, but in a more conventional hierarchy (like in
Tomcat), it breaks very easily.

The default Tomcat configuration uses common-logging with
java.util.logging configured with a custom LogManager I wrote
(otherwise, JUL is totally useless in a container environment).
