Proof step 15 from proof isobj-addobj-01 (previous step)

st[r -- _type] = typeval(mkclasstype(class)), goodfieldsandtypes(r, instfields(class), st), newref(r0, st), r -- _type ∈ st, r ∈ st ⊦ r0 = jvmref, r = jvmref, goodfieldsandtypes(r, instfields(class), addobj(r0, class0, fis, st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ goodfieldsandtypes(r, sks, st) ↔ (∀ sk. sk ∈ sks → goodfieldandtype(r, sk, st))
Proof step 14:
st[r -- _type] = typeval(mkclasstype(class)), goodfieldsandtypes(r, instfields(class), st), newref(r0, st), r -- _type ∈ st, r ∈ st ⊦ r0 = jvmref, r = jvmref, ∀ sk. sk ∈ instfields(class) → goodfieldandtype(r, sk, addobj(r0, class0, fis, st))
