Proof step 12 from proof validmode-addobj (previous step)

newref(r, st) ⊦ _mode ∈ addobj(r, class, fis, st) ∧ validmode(str, addobj(r, class, fis, st)[_mode], addobj(r, class, fis, st)) ↔ validmode(str, st), r = jvmref

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 11:
newref(r, st) ⊦ r = jvmref, _mode ∈ st ∧ validmode(str, st[_mode], addobj(r, class, fis, st)) ↔ validmode(str, st)
