Proof step 62 from proof junkref-addarray-01 (previous step)

newref(refs .first, st), is_classtype(ty), class∃(str, ty .class), junkrefs(str, refs, mkarraytype(ty), addarray(refs .first, ty, vals, st)), ∀ val. val ∈ vals → ¬ junkref(str, val .refval, st) ∧ is_referencevalue(val) ∧ (val .refval ≠ jvmref → st[val .refval -- _type] .type ≤ ty) ⊦ refs .first = jvmref, refs = []

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 61:
refs = r + refs0, newref(r, st), is_classtype(ty), class∃(str, ty .class), junkrefs(str, refs, mkarraytype(ty), addarray(r, ty, vals, st)), ∀ val. val ∈ vals → ¬ junkref(str, val .refval, st) ∧ is_referencevalue(val) ∧ (val .refval ≠ jvmref → st[val .refval -- _type] .type ≤ ty) ⊦ r = jvmref, refs = []
