Class test-bundle defined in two places!?

[svenemtell]

Hi!
I get LispWorks compilation warnings since the class test-bundle is defined in both classes.lisp and test.lisp.
Why is it defined in two places?

Lisp compilation had style-warnings while compiling #<ASDF/LISP-ACTION:CL-SOURCE-FILE "fiveam" "test">
Lisp compilation failed while compiling #<ASDF/LISP-ACTION:CL-SOURCE-FILE "fiveam" "test">

In short the setup looks like this:
make.lisp

...
(ql:quickload :my-system)
(asdf:test-system :my-system)
...

my-system.asd

(defsystem :my-system
  :in-order-to ((test-op (test-op "my-system/test")))
...

(defsystem :my-system/test
  :depends-on (:my-system :fiveam)
  :perform (test-op :after (o s) ...
...

If I explicitly load fiveam (ql:quickload :fiveam) before loading my-system I don't get the warnings, but it shouldn't be necessary to load fiveam explicitly before should it?
