Proof step 7 from proof validrefvalnotnull-put-statfield (previous step)

is_referencevalue(val1), validrefnotnull(str, val1 .refval, ty1, st) ⊦ rk = jvmref -- sk, validrefnotnull(str, val1 .refval, ty1, st[jvmref -- sk, val])

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 6:
val1 = refval(r), is_referencevalue(val1), validrefnotnull(str, r, ty1, st) ⊦ rk = jvmref -- sk, validrefnotnull(str, r, ty1, st[jvmref -- sk, val])

Rule argument
