Proof step 18 from proof isobj-addclass (previous step)

r -- _type ∈ addclass(class0, fis, st) ∧ (∀ sk. sk ∈ sks → goodfieldandtype(r, sk, addclass(class0, fis, st))), st[r -- _type] = typeval(mkclasstype(class)) ⊦ r -- _type ∈ st ∧ (∀ sk. sk ∈ sks → goodfieldandtype(r, sk, st)), r = jvmref, class = class0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
⊦ rk ∈ st → rk ∈ addclass(class, fis, st)
Proof step 17:
st[r -- _type] = typeval(mkclasstype(class)), sk ∈ sks, r -- _type ∈ st, r ∈ st, ∀ sk. sk ∈ sks → goodfieldandtype(r, sk, addclass(class0, fis, st)) ⊦ r = jvmref, class = class0, goodfieldandtype(r, sk, st)
