Proof step 69 from proof junkref-addobj-01 (previous step)

fis .keys = instfields(class), ∃ refs. refs ≠ [] ∧ refs .first = r ∧ junkrefs(str, refs, (addobj(r, class, fis, st)[r -- _type]) .type, addobj(r, class, fis, st)), newref(r, st), class+∃(str, class), validfieldinits(fis, st), ∀ sk, r1. sk × refval(r1) ∈ fis → ¬ junkref(str, r1, st) ⊦ r = jvmref, is_abstract(class)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 68:
fis .keys = instfields(class), newref(refs .first, st), class+∃(str, class), validfieldinits(fis, st), junkrefs(str, refs, mkclasstype(class), addobj(refs .first, class, fis, st)), ∀ sk, r1. sk × refval(r1) ∈ fis → ¬ junkref(str, r1, st) ⊦ refs .first = jvmref, refs = [], is_abstract(class)
