[On the road until later today so just a brief reply]

I think you *are* loading setup.lisp from the jar, and that it contains load-time code that is producing these errors.  To verify that this is indeed the case, I would suggest creating a file with a very simple form, such as 

    (format t “Hello Jar World!~&”) 

to see if that indeed loads.  Then, you know you are successfully loading lisp code from a jar, so what remains is to figure out what the problem is when the rest of your code executes within the jar.

I believe that your error is the result of ASDF attempting to write a fasl in the jar, which is odd as ASDF has ABCL-specific code which should creates the necessary output translation from a jar (which is not a valid target of writes) to the local filesystem.  What’s odd here is that you seem to be using a different version of “asdf.lisp” than what ships with ABCL.  Or is this Quicklisp attempting to install ASDF?  

Any chance of getting a build recipe for the JAR file you are creating here?  Or, barring that, putting a binary up somewhere to inspect?

Setting CL:*LOAD-VERBOSE* to t in ~/.abclrc can also help you get idea of what is being loaded.

Back later,
Mark
