Pathname represents a path to a file or, since recently, an entry in a
Jar file, but it's not able to represent an arbitrary URL.

I know little about OSGi, but probably it requires some special
handling if one wants to explicitly load resources like ABCL does.

As an attempt which I really doubt will work, you can try this:
since what is failing is getLispHome() in class Site, and that can
also use the "abcl.home" system property, you could try to set that
property to "jar:file:/whatever/abcl.jar!/org/armedbear/lisp/" before
loading ABCL and cross your fingers. You'll probably get past the
current failing point but some other things will probably fail. Even
if it works, it's not a good solution at all; still, it might serve as
a temporary hack until we figure out how to behave in a OSGi context.
