Proof step 9 from proof validrefs-primarray (previous step)

st[r -- _type] .type = mkarraytype(ty), st[r -- i '] = refval(r0), validrefs(str, r0 ' + refs, ty, st), 0 ≤ i, 0 < st[r -- _length] .intval, is_primtype(ty), is_array(str, r, st), okreftype(refval(r), mkarraytype(ty), st), r -- _length ∈ st, is_arrayref(r, st[r -- _length] .intval, st), i < st[r -- _length] .intval, r ∈ st, 0 ≤ st[r -- _length] .intval, ∀ j. ¬ j < 0 ∧ ¬ st[r -- _length] .intval ≤ j → okval(st[r -- j '], ty) ⊦ r ' + r0 ' + refs = jvmref ', r = jvmref, is_reftype(ty)
