So tonight I'm seeing an asd file load properly. However loading an
fasl from a subdirectory within a jar file fails.

jar cf test2.jar test.abcl
jar cf test3.jar in/test.lisp
jar cf test4.jar in/test.abcl

(load "jar:file:/Users/alanr/repos/lsw/trunk/patches/test2.jar!/test.abcl")
; Loading jar:file:/Users/alanr/repos/lsw/trunk/patches/test2.jar!/test.abcl ...

; Loading jar:file:/Users/alanr/repos/lsw/trunk/patches/test3.jar!/in/test.lisp
...

java.lang.NullPointerException

I'll see if I can figure if there was something real about the asd
load issue I had yesterday or it was a case of bleary eyes.
