When the LogManager loads classes such as Handlers or configuration classes,
it currently uses Class.forName(). This means that all the loaded classes
must be on the boot classpath.
So to add a new handler class or to add a configuration class, a
customer has to modify the boot classpath, which is pretty undesirable.
The LogManager should instead use the system class path.
