The tests look for NSS libraries on paths described in PKCS11Test.java, i.e.

        osMap.put("Linux-aarch64-64", new String[] {
                "/usr/lib/aarch64-linux-gnu/",
                "/usr/lib/aarch64-linux-gnu/nss/",
                "/usr/lib64/" });

On OL8, not found. It can only pass without doing anything.

On OL9, found. The tests go on and fail with
