Proof step 3 from proof okarray-put-nopath (previous step)

is_valid_ref(str, r0, st), okarray(r, byte_type, st), r ∈ st ⊦ r = jvmref, okarray(r, byte_type, st[r0 -- sk, val]), path∃(str, r, r0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ r ≠ r1 → (okarray(r, ty, st[r1 -- sk, val]) ↔ okarray(r, ty, st))
Proof step 2:
⊦ path∃(str, r, r, st) ↔ r = jvmref ∨ r ≠ jvmref ∧ is_valid_ref(str, r, st)
