Proof step 25 from proof isobj-putbar-01 (previous step)

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

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 7:
⊦ is_obj(r, st) ↔ r ≠ jvmref ∧ r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ∧ is_classtype(st[r -- _type] .type) ∧ is_obj(r, st[r -- _type] .type .class, st)
Proof step 24:
st[r -- _type] = typeval(mkclasstype(class)), r ≠ jvmref ∧ r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ∧ is_classtype(st[r -- _type] .type) ∧ is_obj(r, st[r -- _type] .type .class, st), r -- _type ∈ st, r ∈ st ⊦ r = jvmref, is_obj(r, class, putByteArray(bytes, r1, i, st))
