Proof step 8 from proof is_array-norefval (previous step)

st[r -- _length] = intval(i0), st[r -- _type] = typeval(mkarraytype(ty)), 0 ≤ i0, r -- _type ∈ st, type∃(str, ty), i < i0, is_reftype(ty), r ∈ st, 0 < i0, 0 ≤ i, is_arrayref(r, i0, st), is_integervalue(st[r -- _length]), r -- _length ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i0 ≤ j → is_referencevalue(st[r -- j ']) ⊦ r = jvmref, ty .jtelemtype = void_type, ty .jtelemtype = abstract_type, is_referencevalue(st[r -- i '])

Proof step 7:
st[r -- _type] = typeval(mkarraytype(ty)), st[r -- _length] = intval(i0), 0 < i0, 0 ≤ i0, r -- _length ∈ st, is_arrayref(r, i0, st), 0 ≤ i, r ∈ st, is_reftype(ty), i < i0, type∃(str, ty), r -- _type ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i0 ≤ j → is_referencevalue(st[r -- j ']) ⊦ ty .jtelemtype = abstract_type, ty .jtelemtype = void_type, r = jvmref, is_referencevalue(st[r -- i '])
