Proof step 7 from proof junkrefs-delete (previous step)

st[r0 -- mkfs(class, ty1, fieldvar) '] = refval(r2), st[r0 -- _type] .type ≤ ty, is_obj(str, r0, st), mkfs(class, ty1, fieldvar) ' ∈ instfields(st[r0 -- _type] .type .class), junkrefs(str, r2 ' + refs, ty1, st -- r), ∀ str0, ty0, st0, r1. junkrefs(str0, r2 ' + refs, ty0, st0 -- r1) → r1 = r2 ∨ r1 ∈ refs ∨ junkrefs(str0, r2 ' + refs, ty0, st0) ⊦ r = r0, r0 = jvmref, r = r2, r ∈ refs, junkrefs(str, r2 ' + refs, ty1, st)

Heuristic quantifier closing applied rule all left

And closed the goal!
