Proof step 6 from proof addobj-at-null (previous step)

⊦ r = jvmref, (addobj(r, class, fis, st)[sk]) = st[sk]

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ st[sk] = st[jvmref -- sk]
Proof step 5:
⊦ r = jvmref, (addobj(r, class, fis, st)[jvmref -- sk]) = st[sk]

Rule argument

[speclemmaarg: ,st[sk] = st[jvmref -- sk] ,[sk, st] → [sk, addobj(r, class, fis, st)] ,F ,storefuns , ,lookup-staticfield ]
