Proof step 20 from proof isobj-addobj-01 (conclusion)

⊦ ¬ is_obj(r, class, addobj(r0, class0, fis, st)) ∧ newref(r0, st) → ¬ is_obj(r, class, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 19:
is_obj(r, class, st), newref(r0, st) ⊦ r0 = jvmref, is_obj(r, class, addobj(r0, class0, fis, st))

Rule argument
