Proof step 20 from proof del-addobj (previous step)

newref(r, st) ⊦ ∀ rk. (rk ∈ addobj(r, class, fis, st) -- r ↔ rk ∈ st) ∧ (addobj(r, class, fis, st) -- r)[rk] = st[rk], r = jvmref

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 19:
newref(r, st) ⊦ r = jvmref, (rk ∈ addobj(r, class, fis, st) -- r ↔ rk ∈ st) ∧ (addobj(r, class, fis, st) -- r)[rk] = st[rk]
