Hello,

I have noticed these warning after I performed an Hudson upgrade from 1.317 to
1.318

SLF4J: This version of SLF4J requires log4j version 1.2.12 or later. See also
http://www.slf4j.org/codes.html#log4j_version

I am now at Hudson version 1.323 and still seeing the warnings. the current
bundled log4j jar file is at version 1.2.9.

would it be possible to upgrade to 1.2.12? the latest stable version for log4j
is 1.5.8 but I am not sure if it will introduce breaking changes.
