Proof step 8 from proof isobj-addarray-other-01 (previous step)

st[r -- _type] = typeval(mkclasstype(class)), ∀ sk. sk ∈ instfields(class) → goodfieldandtype(r, sk, st), r -- _type ∈ st, r ∈ st ⊦ r = r0, r = jvmref, ∀ sk. sk ∈ instfields(class) → goodfieldandtype(r, sk, addarray(r0, ty0, vals, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
⊦ r ≠ r0 → (goodfieldandtype(r0, sk, addarray(r, ty, vals, st)) ↔ goodfieldandtype(r0, sk, st))
Proof step 7:
st[r -- _type] = typeval(mkclasstype(class)), sk ∈ instfields(class), r -- _type ∈ st, r ∈ st, ∀ sk. sk ∈ instfields(class) → goodfieldandtype(r, sk, st) ⊦ r = r0, r = jvmref, goodfieldandtype(r, sk, st)
