Thanks for your response, Ylan. That is, indeed, a space. The JAR spec
dictates that individual paths need to be separated by one or more
spaces (see
http://java.sun.com/j2se/1.4/docs/guide/jar/jar.html#JAR%20Manifest for
more info), so in our case we're designating the current directory as
the first path to search, and ./lib/log4j.jar as the second. We
actually did try removing that period and space to see if it made a
difference, and, unfortunately, it doesn't.
In regard to your observation related to log4j, you might notice in the
source code in the main method that we're being lazy and simply
initializing log4j with
BasicConfigurator.configure();
rather than bothering with a configuration file.
