Proof step 6 from proof validrefnotnull-put-statfield-01 (previous step)

rk1 .ref = jvmref, validrefnotnull(str, r, ty1, st) ⊦ validrefnotnull(str, r, ty1, st[rk1, val])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Rule argument

[speclemmaarg: ,r = rk .ref ∧ sk = rk .key ↔ rk = r -- sk ,[rk, r, sk] → [rk1, r0, sk] ,T ,refkey , ,elim ]
