Proof step 8 from proof gft-out (previous step)

⊦ r = jvmref, r -- fs ' ∈ st[_out, val] ∧ okval(st[_out, val][r -- fs '], fs .type) ↔ r -- fs ' ∈ st ∧ okval(st[r -- fs '], fs .type)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 7:
fs = mkfs(class, ty, fieldvar) ⊦ r = jvmref, r -- fs ' ∈ st[_out, val] ∧ okval(st[_out, val][r -- fs '], ty) ↔ r -- fs ' ∈ st ∧ okval(st[r -- fs '], ty)

Rule argument
