Proof step 9 from proof okarray-init-basic-01 (previous step)

∀ j0. ¬ j0 < 0 ∧ ¬ i ≤ j0 → oktype(st[r -- j0 '], ty, st), st[r -- _length] = intval(i), okreftype(refval(r), mkarraytype(ty), st), is_arrayref(r, i, st), r -- _length ∈ st, 0 ≤ i, r ∈ st ⊦ ∀ j. 0 ≤ j ∧ j < i → oktype(st[r -- j '], ty, st), r = jvmref, r = r0, is_classtype(ty), is_arraytype(ty)

And obtained the following new goals

Proof step 8:
st[r -- _length] = intval(i), j < i, okreftype(refval(r), mkarraytype(ty), st), is_arrayref(r, i, st), r -- _length ∈ st, 0 ≤ i, r ∈ st, 0 ≤ j, 0 < i, ∀ j0. ¬ j0 < 0 ∧ ¬ i ≤ j0 → oktype(st[r -- j0 '], ty, st) ⊦ r = jvmref, r = r0, oktype(st[r -- j '], ty, st), is_classtype(ty), is_arraytype(ty)
