Proof step 50 from proof junkrefs-union (previous step)

st[r -- i '] = refval(r0), 0 < st[r -- _length] .intval, r ∈ st, st[r -- _type] .type ≤ ty, 0 ≤ i, is_array(str, r, st), i < st[r -- _length] .intval, junkrefs(str, r0 ' + refs, st[r -- _type] .type .type, st0 ∪ st), r -- _length ∈ st, r -- _type ∈ st, r -- i ' ∈ st, ∀ str0, ty0, st1, st2. junkrefs(str0, r0 ' + refs, ty0, st1 ∪ st2) → junkrefs(str0, r0 ' + refs, ty0, st2) ⊦ r = jvmref, junkrefs(str, r0 ' + refs, st[r -- _type] .type .type, st)

Heuristic quantifier closing applied rule all left

And closed the goal!
