Proof step 4 from proof validsubset-addobj (previous step)

fis .keys = instfields(class), junkref(str, r, addobj(r, class, fis, st)), class+∃(str, class), validfieldinits(fis, st), class∃(str, class), newref(r, st), ∀ sk, r1. sk × refval(r1) ∈ fis → ¬ junkref(str, r1, st) ⊦ r = jvmref, r ∈ st, is_abstract(class)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ newref(r, st) ∧ class+∃(str, class) ∧ fis .keys = instfields(class) ∧ validfieldinits(fis, st) ∧ ¬ is_abstract(class) ∧ (∀ sk, r1. sk × refval(r1) ∈ fis → ¬ junkref(str, r1, st)) → ¬ junkref(str, r, addobj(r, class, fis, st))

Rule argument

[crewrite-arg: junkref-addobj-01 , F , [st, fis, class, r, str] → [st, fis, class, r, str] ]
