Proof step 6 from proof validref-put-statfield-02 (previous step)

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

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 5:
rk1 = r0 -- sk, r0 = jvmref, validref(str, r, ty1, st[rk1, val]) ⊦ validref(str, r, ty1, st)

Rule argument
