Proof step 13 from proof isobj-addarray (previous step)

st[r1 -- _type] = typeval(mkclasstype(class)), r1 -- _type ∈ st, ∀ sk. sk ∈ instfields(class) → goodfieldandtype(r1, sk, addarray(r0, ty, vals, st)), r1 ∈ st, sk ∈ instfields(class) ⊦ r1 = jvmref, r1 = r0, goodfieldandtype(r1, sk, st)

And obtained the following new goals

Proof step 11:
⊦ r ≠ r0 → (goodfieldandtype(r0, sk, addarray(r, ty, vals, st)) ↔ goodfieldandtype(r0, sk, st))
Proof step 12:
st[r1 -- _type] = typeval(mkclasstype(class)), r1 -- _type ∈ st, r1 ∈ st, sk ∈ instfields(class), ∀ sk0. sk0 ∈ instfields(class) → goodfieldandtype(r1, sk0, st) ⊦ r1 = jvmref, r1 = r0, goodfieldandtype(r1, sk, st)
