This error is not specific to Haiku. The very same error also appears when try to bootstrap SBCL with ABCL 1.6.0 on Linux and doesn't appear when bootstrapping with ABCL 1.5.0.

Currently, ABCL is the only way to run Common Lisp on Haiku
(https://www.haiku-os.org/). I try to bootstrap SBCL on Haiku usinbg
ABCL. Previously, bootstrap (first stage of compilation) was possible
with ABCL 1.5.0. Now with ABCL 1.6.0 the compilation fails with the
attached Java error. This is a regression fomr 1.5.0.
