Obter xml de resposta da API

Oi pessoal, estou a alguns dias tentando obter o retorno da API em XML quando ocorrer um ERRO, porém nada é retornado, quando a requisição dá certo funciona normalmente. Meu código é este:

public  static  void  main ( String args []) throws Exception  
        { 
          operacaoSerasa();
        } 
      public static void operacaoSerasa() throws Exception {
            URL url = new URL("https://treina.spc.org.br/spc/remoting/ws/insumo/spc/spcWebService?wsdl\"");
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            String requestBodyXML = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:web=\"http://webservice.spc.insumo.spcjava.spcbrasil.org/\"> <soapenv:Header/> <soapenv:Body> <web:incluirSpc> <insumoSpc> <tipo-pessoa>J</tipo-pessoa> <dados-pessoa-juridica> <cnpj numero=\"30585461000134\"/> <razao-social> IMPORTADORA MACAPA RURAL CASA E CONSTRUCAO LTDA </razao-social> <nome-comercial>IMPORTADORA MACAPA, RURAL CASA E CONSTRUCAO</nome-comercial> </dados-pessoa-juridica> <data-compra>2022-07-29T00:00:00</data-compra> <data-vencimento>2022-11-17T00:00:00</data-vencimento> <codigo-tipo-devedor>C</codigo-tipo-devedor> <numero-contrato>30585461000134C947272</numero-contrato> <valor-debito> 1436.08</valor-debito> <natureza-inclusao> <id>1</id> </natureza-inclusao> <endereco-pessoa> <cep>-68905627</cep> <logradouro>JOSE DO ESPIRITO SANTO ARAUJO</logradouro> <bairro>PERPETUO SOCORRO</bairro> <numero>283</numero> </endereco-pessoa> </insumoSpc> </web:incluirSpc> </soapenv:Body> </soapenv:Envelope>";
            StringBuffer response = new StringBuffer();
            String inputLine = "";
            //connection.setRequestProperty("Content-Type", "application/xml");
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Authorization", "Basic MTEyMDIy");
            connection.setRequestProperty("Content-Length", "<calculated when request is sent>");
            connection.setRequestProperty("Host", "<calculated when request is sent>");
            connection.setRequestProperty("User-Agent", "PostmanRuntime/7.29.2");
            connection.setRequestProperty("Accept", "application/xml?");
            connection.setRequestProperty("Connection", "keep-alive");
            connection.setRequestProperty("Content-Type", "text/xml charset=utf-8");

            connection.setDoOutput(true);
            connection.setReadTimeout(30000);
            connection.setConnectTimeout(30000);

            DataOutputStream wr = new DataOutputStream(connection.getOutputStream());
            wr.writeBytes(requestBodyXML);
            wr.flush();
            wr.close();

            try {
                int responseCode = connection.getResponseCode();

                BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream(), "utf-8"));
                 if (responseCode == HttpURLConnection.HTTP_OK && 
                     responseCode == HttpURLConnection.HTTP_CREATED || 
                     responseCode == HttpURLConnection.HTTP_ACCEPTED) {
                     throw new Exception("Erro de conexão, veja mais informações: ");
                 }
                 while ((inputLine = in.readLine()) != null) {
                     response.append(inputLine);
                 }
                 in.close();

            } catch (Exception erro) {

                throw new Exception("<br>Cód. Resposta Servidor: " + connection.getResponseCode() + "<br/>"
                                         + erro.toString() + "<br/>" + response.toString() 
                                         + connection.getErrorStream() );

            } finally {
                connection.disconnect();
            }
        }

O erro que eu recebo não é um XML dentro do Eclipse.

O erro é proposital, retorno da API no Postman:

<?xml version="1.0" ?>

    <S:Body>
        <S:Fault xmlns:ns4="http://www.w3.org/2003/05/soap-envelope">

            <faultstring>
                <![CDATA[Operador ou senha inválidos. Tente novamente.]]>
