Proof step 69 from proof sharing-pathex-field-self-01 (previous step)

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

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 68:
refs = r + refs0, r = st[refs .last -- fs '] .refval, is_classtype(st[refs .last -- _type] .type), fs ' ∈ instfields(st[refs .last -- _type] .type .class), validrefs(str, refs, mkclasstype(`java.lang.Object' .class), st) ⊦ refs = [], refs .last = jvmref, hasSharing(refs .last, st)
