Proof step 27 from proof okarray-copy (previous step)

⊦ r1 = r0, r1 -- _type ∈ st ∧ is_typevalue(st[r1 -- _type]) ∧ is_arraytype(st[r1 -- _type] .type) ∧ st[r1 -- _type] .type .type ≤ ty ∧ r1 ≠ jvmref ∧ r1 -- _length ∈ st ∧ is_integervalue(st[r1 -- _length]) ∧ 0 ≤ st[r1 -- _length] .intval ∧ is_arrayref(r1, st[r1 -- _length] .intval, st) ∧ (∀ j0. ¬ j0 < 0 ∧ ¬ st[r1 -- _length] .intval ≤ j0 → okval(st[r1 -- j0 '], ty)) ↔ okarray(r1, ty, st)

And obtained the following new goals

Proof step 5:
⊦ okarray(r, ty, st) ↔ okreftype(refval(r), mkarraytype(ty), st) ∧ r ≠ jvmref ∧ r -- _length ∈ st ∧ is_integervalue(st[r -- _length]) ∧ 0 ≤ st[r -- _length] .intval ∧ is_arrayref(r, st[r -- _length] .intval, st) ∧ (∀ j. 0 ≤ j ∧ j < st[r -- _length] .intval → oktype(st[r -- j '], ty, st))
Proof step 26:
⊦ r1 = r0, r1 -- _type ∈ st ∧ is_typevalue(st[r1 -- _type]) ∧ is_arraytype(st[r1 -- _type] .type) ∧ st[r1 -- _type] .type .type ≤ ty ∧ r1 ≠ jvmref ∧ r1 -- _length ∈ st ∧ is_integervalue(st[r1 -- _length]) ∧ 0 ≤ st[r1 -- _length] .intval ∧ is_arrayref(r1, st[r1 -- _length] .intval, st) ∧ (∀ j0. ¬ j0 < 0 ∧ ¬ st[r1 -- _length] .intval ≤ j0 → okval(st[r1 -- j0 '], ty)) ↔ okreftype(refval(r1), mkarraytype(ty), st) ∧ r1 ≠ jvmref ∧ r1 -- _length ∈ st ∧ is_integervalue(st[r1 -- _length]) ∧ 0 ≤ st[r1 -- _length] .intval ∧ is_arrayref(r1, st[r1 -- _length] .intval, st) ∧ (∀ j. 0 ≤ j ∧ j < st[r1 -- _length] .intval → oktype(st[r1 -- j '], ty, st))
