You could try using a custom repository selector
that is keyed by thread. Log4j-1.3 has one keyed
by JNDI. Others out there are keyed by
ClassLoader, but that just leads to classloading
issues. Look up in your favorite search engine
or in the Log4j Wiki. The Log4j -sandbox used to
have one that used JNDI and was compatible with
Log4j 1.2, but since an equivalent one was added
to Log4j 1.3 (albeit incompatible with Log4j
1.2), it was removed. It was tagged as something
like 0.[1|2|3|4]alpha, so you might find it by
looking at that tags in SVN if the conversion from CVS to SVN saved the tags.
