Proof step 15 from proof validrefkeynotnull-has-field (previous step)

is_referencevalue(st[rk]), validrefnotnull(str, st[rk] .refval, mkclasstype(class), st), rk ∈ st, sk ∈ instfields(class), is_fskey(sk) ⊦ st[rk] .refval = jvmref, st[rk] .refval -- sk ∈ st

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 14:
st[rk] = refval(r), is_referencevalue(st[rk]), validrefnotnull(str, r, mkclasstype(class), st), rk ∈ st, sk ∈ instfields(class), is_fskey(sk) ⊦ r = jvmref, r -- sk ∈ st
