Proof step 18 from proof sharing-pathex-field-self (previous step)

r = st[r -- fs '] .refval, validrefs(`docs2store', r ', mkclasstype(`java.lang.Object' .class), st), fs ' ∈ instfields(st[r -- _type] .type .class), is_classtype(st[r -- _type] .type) ⊦ r = jvmref, hasSharing(r, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 17:
st[r -- fs '] = refval(r0) ∧ is_referencevalue(st[r -- fs ']), r = r0, validrefs(`docs2store', r ', mkclasstype(`java.lang.Object' .class), st), fs ' ∈ instfields(st[r -- _type] .type .class), is_classtype(st[r -- _type] .type) ⊦ r = jvmref, hasSharing(r, st)
