Proof step 24 from proof isobj-addarray (previous step)

st[r1 -- _type] .type = mkclasstype(class), r1 ∈ st, is_obj(r1, class, addarray(r0, ty, vals, st)), is_typevalue(st[r1 -- _type]), r1 -- _type ∈ st ⊦ r1 = jvmref, r1 = r0, is_obj(r1, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 23:
st[r1 -- _type] = typeval(ty0), ty0 = mkclasstype(class), r1 ∈ st, is_obj(r1, class, addarray(r0, ty, vals, st)), is_typevalue(st[r1 -- _type]), r1 -- _type ∈ st ⊦ r1 = jvmref, r1 = r0, is_obj(r1, st)
