Proof step 128 from proof compat-addobj (previous step)

And obtained the following new goals

Proof step 127:
sk .fs = mkfs(class1, ty, fieldvar), st[r0 -- _type] = typeval(mkclasstype(class0)), sk ∈ instfields(class0), r0 ∈ st, r0 -- _type ∈ st, compatstatic(str, st), compatmode(str, st), newref(r, st), is_predefined_class(class), compatfields(str, r0, instfields(class0), st), class+∃(str, class0) ⊦ r0 = jvmref, r = jvmref, r0 -- sk ∈ addobj(r, class, [], st) ∧ ¬ is_indexkey(sk) ∧ compat(str, st[r0 -- sk], ty, addobj(r, class, [], st))
