Ok, I understand more now... though you know that log4j.properties is going to
be used even before ServerImpl gets created right...
It looks like the UCL bits should be operable at the time when Log4jService is
created... the TCL is set right before it is started. But I would guess
(since I am not a CL expert) that since we have not processed the classpath
element from jboss-service.xml, we have not populated the UCL repo with
anything useful, short of the conf directory (as set by
ServerImpl.initBootLibraries()).
If there were UCL's for each registered boot library, would the UCL be used,
or would the URLCL be used?
If the UCL will be used, then what problems would arise if we either installed
a UCL for each URLCL, or rather than using a URLCL, use a boot strap UCL,
which will only load the required boot classes from the URLCL, then once the
repo is active will force all classes to go through it. This will mean that
classes loaded on the URLCL will be serialized right... but we don't really
care too much about that.
If the above makes sence, then I think it would be worth the effort to
implement that rather than add to the logging configuration complexity... but
I am not sure if the above will work.
