Error while retrieving Web Service Object List (CSV)

Question

I have an error retrieving a list of CSV objects from the server.. I’m using Jsefa to serialize and deserialize Java Beans for CSV and implemented a Messagebodywriter and Reader to make this conversion in calls..

The detail is that I am unable to convert this list to objects using jersey’s Generictype..

private void listAsResponse(String mediaType) {
    Response response = target().path("produto").path("all")
            .request(mediaType).get();
    System.out.println(response.getEntity());
}

private void listAsString(String mediaType) {
    String req = target().path("produto").path("all")
            .request(mediaType).get(String.class);
    System.out.println(req);
}

//O erro ocorre nesta chamada aqui, as acima executam normalmente..
private void listAsObject(String mediaType) {
    List<ProdutoDTO> produtos = target().path("produto").path("all")
            .request(mediaType).get(new GenericType<List<ProdutoDTO>>(){});
    System.out.println(produtos);
}

Does anyone have any idea why? I am using JSON and XML as well and in these two cases I can run this test normally, only with the CSV that the error occurs (no listAsObject)..
