So, 2 issues:
1) Do we remove org.apache.commons.logging from FilteredPackages?
I've attached 2 files showing what happens if you do this in 4.0.5 and
4.0.2 and then deploy a war with commons-logging.jar included. The
4.0.2 one shows a JaccContextValve failure that was likely the thing
that led to filtering the packages.
In 4.2, this works fine.
IMHO, if a quick perusal of the attached files by you and Scott isn't
enough to decide to remove the filtering of JCL packages, we should
leave them filtered. That's a conservative approach, which is fine when
we have lots of other things to worry about.
2) Patching JCL 1.1 to do late binding of log4j. That's useful, if for
nothing else to support consistent behavior from 4.0.x to 4.2.0 for wars
that bundle log4j but not commons-logging.jar. Definitely needed if we
decide to keep the jcl package filtering. The JIRA to do the patch was
assigned by you to you, so I guess you volunteered ;)
You're my boss, so feel free to assign it to me. :-) But I won't touch
it until the EJB3 stuff and shared sessions are done.
