Proof step 15 from proof junkref-ac (previous step)

sk = fs ', fs = mkfs(class, ty, fieldvar), is_fskey(sk), ∀ r, str, class, st. r = jvmref ∨ (junkref(str, r, addclass(class, fis0, st)) ↔ junkref(str, r, st)) ⊦ junkref(str, r, addclass(class, (sk × val) ' + fis0, st)) ↔ junkref(str, r, st), r = jvmref

Proof step 14:
∀ r, str, class, st. r = jvmref ∨ (junkref(str, r, addclass(class, fis0, st)) ↔ junkref(str, r, st)) ⊦ junkref(str, r, addclass(class, (mkfs(class, ty, fieldvar) ' × val) ' + fis0, st)) ↔ junkref(str, r, st), r = jvmref
