That's incorrect. It is provided as a distinct .abcl file for each
.lisp file, which is a zip containing a text file (generated from the
top-level forms in the .lisp file) + a .cls file for each function
(top-level or non-inlined local) in the .lisp file. .cls files are in
JVM class file format, but they're not loadable as-is because they
don't obey the JVM naming conventions (they ought to be ending in
.class and placed in a org/armedbear/lisp/ directory).
What you *can* do is package .abcl files in a .jar file and use ASDF
to load them with a single function call.
