Proof step 5 from proof sharing-twopaths (previous step)

st[r -- sks] .refval = st[r -- sks0] .refval, fits(r, sks0, st), fits(r, sks, st), validrefs(str, st[r -- sks0] .refval ', mkclasstype(`java.lang.Object' .class), st) ⊦ r = jvmref, sks = sks0, sks = [], sks0 = [], st[r -- sks0] .refval = jvmref, st[r -- sks] = st[r -- sks0], sks ⊑ sks0

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 4:
st[r -- sks] = refval(r0) ∧ is_referencevalue(st[r -- sks]), r0 = st[r -- sks0] .refval, fits(r, sks0, st), fits(r, sks, st), validrefs(str, st[r -- sks0] .refval ', mkclasstype(`java.lang.Object' .class), st) ⊦ r = jvmref, sks = sks0, sks = [], sks0 = [], st[r -- sks0] .refval = jvmref, st[r -- sks] = st[r -- sks0], sks ⊑ sks0
