Proof step 9 from proof isobj-del-01 (previous step)

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

User applied rule all left

And obtained the following new goals

Proof step 8:
st[r -- _type] = typeval(mkclasstype(class)), r ∈ st, r -- _type ∈ st, sk ∈ instfields(class), sk ∈ instfields(class) → goodfieldandtype(r, sk, st) ⊦ r = r0, r = jvmref, goodfieldandtype(r, sk, st -- r0)
