Actually, I think there is something else wrong.  I just looked at the last Gump run for VFS2
and it is complaining that there are multiple SLF4J bindings. The first is coming from slf4j-log4j12
which I believe binds SLF4j to Log4j.  The second is coming from Jackrabbit itself. I did
a jar -tf on jackrabbit-standalone-1.6.5.jar and it includes a whole pile of  classes that
aren't from Jackrabbit. I believe Gary added this to be able to test WebDAV directly during
the build. I have no idea why we don't encounter any errors during the normal build as -X
shows both jars are present on the test class path.
