Background: jakarta-velocity is about to ship a release. It now uses
jakarta-log4j. It is often used in combination with other subprojects.
And some of the methods velocity uses from log4j were just removed.
This means that we either need to tell people not to upgrade to the latest
log4j until everybody can (a logistical nightmare), get log4j to support
the old interfaces for a period of time in a deprecated fashion, or we need
to find a technique that velocity can use that works with both the prior
and intended future releases of log4j.
If we don't do one of these three things, then the first log4j in the
classpath will likely break somebody.
Note: due to a stupid error on my part, the last gump run didn't pick up
the recent changes to the project definitions. Here is the set of errrors
that would have been found:
