Proof step 45 from proof addclass-okarray (conclusion)

⊦ okarray(r, ty, addclass(class, fis, st)) ↔ okarray(r, ty, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ 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 44:
⊦ okreftype(refval(r), mkarraytype(ty), addclass(class, fis, st)) ∧ r ≠ jvmref ∧ r -- _length ∈ addclass(class, fis, st) ∧ is_integervalue(addclass(class, fis, st)[r -- _length]) ∧ 0 ≤ (addclass(class, fis, st)[r -- _length]) .intval ∧ is_arrayref(r, (addclass(class, fis, st)[r -- _length]) .intval, addclass(class, fis, st)) ∧ (∀ j. 0 ≤ j ∧ j < (addclass(class, fis, st)[r -- _length]) .intval → oktype(addclass(class, fis, st)[r -- j '], ty, addclass(class, fis, st))) ↔ okarray(r, ty, st)
