Proof step 21 from proof isobj-putbar-01 (previous step)

st[r -- _type] = typeval(mkclasstype(class)), r ∈ st, r -- _type ∈ st, is_obj(r, class, st) ⊦ r = jvmref, goodfieldsandtypes(r, instfields(class), putByteArray(bytes, r1, i, st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 10:
⊦ is_obj(r, class, st) ↔ r ≠ jvmref ∧ (r -- _type) × typeval(mkclasstype(class)) ∈ st ∧ goodfieldsandtypes(r, instfields(class), st)
Proof step 20:
st[r -- _type] = typeval(mkclasstype(class)), r ∈ st, r -- _type ∈ st, r ≠ jvmref ∧ (r -- _type) × typeval(mkclasstype(class)) ∈ st ∧ goodfieldsandtypes(r, instfields(class), st) ⊦ r = jvmref, goodfieldsandtypes(r, instfields(class), putByteArray(bytes, r1, i, st))
