Proof step 12 from proof validrefkeynotnull-notnewref (previous step)

st[rk] = refval(r) ∧ is_referencevalue(st[rk]), validrefkeynotnull(str, rk, ty, st), newref(r, st) ⊦

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 11:
st[rk] = refval(r), newref(r, st), validrefkeynotnull(str, rk, ty, st) ⊦ r = jvmref

Rule argument
