Proof step 15 from proof isarray-put-field (previous step)

And obtained the following new goals

Proof step 14:
st[r -- _length] = intval(i), st[r -- _type] = typeval(mkarraytype(ty)), r -- _type ∈ st[r0 -- fs ', val], r -- _length ∈ st[r0 -- fs ', val], is_integervalue(st[r -- _length]), is_arrayref(r, i, st), r -- _length ∈ st, r -- _type ∈ st, r ∈ st[r0 -- fs ', val], 0 ≤ i, r ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → okval(st[r -- j '], ty) ⊦ r = jvmref, fs ' = _length, fs ' = _type, (0 ≤ j ∧ j < i → okval(st[r -- j '], ty)) ∧ okreftype(refval(r), mkarraytype(ty), st)
