Proof step 45 from proof subset-okarray (previous step)

st ⊆ st0, okarray(r, ty, st), r ∈ st ⊦ r = jvmref, okarray(r, ty, st0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ st1 ⊆ st2 ↔ (∀ rk. rk ∈ st1 → rk ∈ st2 ∧ st1[rk] = st2[rk])
Proof step 44:
∀ rk. rk ∈ st → rk ∈ st0 ∧ st[rk] = st0[rk], okarray(r, ty, st), r ∈ st ⊦ r = jvmref, okarray(r, ty, st0)
