Proof step 7 from proof addclass-union-sw (previous step)

⊦ st[jvmref -- sk] = noval, jvmref ∈ st, jvmref -- sk ∈ addclass(class0, fis0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ ¬ rk ∈ st → st[rk] = ∅[rk]
Proof step 6:
⊦ rk ∈ st → rk ∈ addclass(class, fis, st)

Rule argument
