Proof step 45 from proof putbar-classfield-onlymod (previous step)

is_classtype(st[r -- _type] .type), sk ∈ instfields(st[r -- _type] .type .class), okbytearray(st[r -- sk] .refval, st) ⊦ r = jvmref, onlyModified(str, r, st, putByteArray(bytes, st[r -- sk] .refval, st)), junkref(str, r, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 44:
st[r -- sk] = refval(r0) ∧ is_referencevalue(st[r -- sk]), is_classtype(st[r -- _type] .type), sk ∈ instfields(st[r -- _type] .type .class), okbytearray(r0, st) ⊦ r = jvmref, onlyModified(str, r, st, putByteArray(bytes, r0, st)), junkref(str, r, st)
