Proof step 6 from proof validref-addobj-this (previous step)

ty = mkclasstype(class0), fis .keys = instfields(class), newref(r, st), validfieldinits(fis, st), class+∃(str, class), class∃(str, class), type∃(str, ty), is_classtype(ty), class ≤ class0, ∀ sk, r1. sk × refval(r1) ∈ fis → ¬ junkref(str, r1, st) ⊦ r = jvmref, validref(str, r, ty, addobj(r, class, fis, st)), is_abstract(class)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 5:
fis .keys = instfields(class), class ≤ class0, newref(r, st), validfieldinits(fis, st), class+∃(str, class), class∃(str, class), tdname+∃(str, class0), ∀ sk, r1. sk × refval(r1) ∈ fis → ¬ junkref(str, r1, st) ⊦ r = jvmref, validref(str, r, mkclasstype(class0), addobj(r, class, fis, st)), is_abstract(class)
