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

¬ (is_referencevalue(st[r -- i ']) ∧ ¬ is_reftype(st[r -- _type] .type .type) ∧ 0 ≤ i ∧ i < st[r -- _length] .intval), st[r -- _type] .type = mkarraytype(ty0), st[r -- i '] = refval(r0), junkrefs(str, r0 ' + refs0, ty0, st), okarray(r, ty, st), is_array(str, r, st), is_primtype(ty), ty0 ≤ ty, 0 ≤ i, 0 < st[r -- _length] .intval, r ∈ st, i < st[r -- _length] .intval ⊦ r = jvmref

And obtained the following new goals

Proof step 6:
st[r -- i '] = refval(r0), st[r -- _type] .type = mkarraytype(ty0), i < st[r -- _length] .intval, r ∈ st, 0 < st[r -- _length] .intval, 0 ≤ i, ty0 ≤ ty, is_primtype(ty), is_array(str, r, st), okarray(r, ty, st), junkrefs(str, r0 ' + refs0, ty0, st), is_reftype(ty0) ⊦ r = jvmref
