"code base" is generally the URL of the class path entry itself.  It's
mainly defined in the specification for java.lang.ClassLoader.

The specification is pretty clear, and doesn't seem unintentional.
Relative URLs have a very specific normative definition.  It's very
unambiguous; the code just doesn't work the way the specification says
it should.
