Proof step 9 from proof isobj-put-02 (previous step)

st[r -- _type] .type = mkclasstype(class0), r -- _type ∈ st, is_typevalue(st[r -- _type]), is_classtype(st[r -- _type] .type), is_obj(r, class0, st), okval(val, ty), r ∈ st ⊦ ty = void_type, r = jvmref, is_obj(r, st[r1 -- mkfs(class, ty, fieldvar) ', val])
