Pessoal, estou tendo o seguinte problema ao consumir um webservice do gerenciaNet.
Alguém tem ideia do que seja?

package br.comgerencianet;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.net.URL;
import java.util.Base64;

import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLSocketFactory;

public class Auth {
  public static void main(String[] args) throws Exception {
      String client_id = "CÓDIGO AQUI";
      String client_secret = "CÓDIGO AQUI";;
      String basicAuth = Base64.getEncoder().encodeToString(((client_id+':'+client_secret).getBytes()));
    

      System.setProperty("javax.net.ssl.keyStore", "\r\n"
      		+ "C:\\Users\\cleit\\OneDrive\\Área de Trabalho\\Cleiton Conceição\\homologacao-273143-ATIVO.p12"); 
      SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
      
      URL url = new URL ("https://sandbox.gerencianet.com.br/v1/authorize"); //Para ambiente de Desenvolvimento              
      HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
      conn.setDoOutput(true);
      conn.setRequestMethod("POST");
      conn.setRequestProperty("Content-Type", "application/json");
      conn.setRequestProperty("Authorization", "Basic "+ basicAuth);
      conn.setSSLSocketFactory(sslsocketfactory);
      String input = "{\"grant_type\": \"client_credentials\"}";
     
      OutputStream os = conn.getOutputStream();
      os.write(input.getBytes());
      os.flush();     

      InputStreamReader reader = new InputStreamReader(conn.getInputStream());
      BufferedReader br = new BufferedReader(reader);

      String response;
      while ((response = br.readLine()) != null) {
        System.out.println(response);
      }
      conn.disconnect();

  }
}

Nessa parte:

System.setProperty("javax.net.ssl.keyStore", "\r\n"
  + "C:\\Users\\cleit\\OneDrive\\Área de Trabalho\\Cleiton Conceição\\homologacao-273143-ATIVO.p12");

Esse \r\n é necessário mesmo? Acho que seria só assim:

System.setProperty("javax.net.ssl.keyStore", "C:\\Users\\cleit\\OneDrive\\Área de Trabalho\\Cleiton Conceição\\homologacao-273143-ATIVO.p12");

Possivelmente não seja a causa do erro, mas vai que é neh.
