That may be. ABCL is running on the host system and can reuse it, but it aims to be a full implementation of Common Lisp, not a blend of a subset of Lisp plus the host runtime. For example one would expect the full Common Lisp numerics.
One of its purposes is to be able to run portable Common Lisp code on the JVM. Like Maxima or like bootstrapping the SBCL system.
There is a bit more about the interop in the repository and in the manual:
