Error 500 in JsonObjectRequest in Android

Question

I'm struggling with error 500 during sending a JSON Object to my Server. I'm using POST method because I need to save user in the database. I suppose something is wrong in my request cause the output doesn't print (in onResponse method). On the server side, the data is not printed too but there is no exception handled, no errors - everything going okay but data is still not there!

Android register method:

public class RegisterIndividualActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_register_individual);
        setListeners();
    }

    private void setListeners() {
        final EditText loginField = (EditText) findViewById(R.id.loginField);
        final EditText passwordField = (EditText) findViewById(R.id.passwordField);

        Button registerButton = (Button) findViewById(R.id.registerButton);

        registerButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                register(
                        loginField.getText(),
                        passwordField.getText(),
                );
            }
        });
    }

    private void register(final Editable login,
                          final Editable password){
        final ProgressDialog progressDialog = new ProgressDialog(this);
        progressDialog.setMessage("Creating new acc...");
        progressDialog.show();

        RequestQueue queueAcc = Volley.newRequestQueue(this);
        String urlAcc = getResources().getString(R.string.server_address)+"android/user/register?login="
                + login.toString() + "&password=" + password.toString();


        JSONObject newUser = new JSONObject();
        try {
            newUser.put("login", login.toString());
            newUser.put("password", password.toString());
        } catch (JSONException e) {
            e.printStackTrace();
        }
        System.out.println("USER TO SAVE: " + newUser.toString());
        JsonObjectRequest urlAccStringRequest = new JsonObjectRequest(Request.Method.POST, urlAcc, newUser, new Response.Listener() {
            @Override
            public void onResponse(JSONObject response) {
                        System.out.println("Good morning " + login.toString()); //doesnt print

                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) { //i got this error
                progressDialog.dismiss();
                Toast.makeText(RegisterIndividualActivity.this, "Connection error", Toast.LENGTH_SHORT).show();
            }
        });

        queueAcc.add(urlAccStringRequest);

        queueAcc.start();
    }
}

The controller on the server side (this is in proper class with @Controller adnotation and needed mapping which is android/user):

@RequestMapping(value = "/register", method = RequestMethod.POST)
public void register(
        @RequestParam("login") String login,
        @RequestParam("password") String password,
        HttpServletRequest request, HttpServletResponse response, Model model
){
    System.out.println("
In Register method..");
    UserModel uM = new UserModel();
    HttpSession session = request.getSession(true);
    response.setContentType("application/json");
    response.setCharacterEncoding("UTF-8");
    uM.setAccountType("Client");
    JsonParser parser = new JsonParser();
    try {
        System.out.println("
Trying to save..");
        JsonObject jsonObject = (JsonObject) parser.parse(request.getReader());
        System.out.println(jsonObject.get("login").toString()); //event this doesnt print
        uM.setLogin(jsonObject.get("login").toString());
        uM.setPassword(jsonObject.get("password").toString());
        System.out.println(uM.toString()); //doesnt print
        userDAO.save(uM);
    } catch (IOException e) { // doesnt throw exception
        e.printStackTrace();
    }


    System.out.println(uM.toString()); // doesnt print

}

@EDIT Added server log:

@EDIT 2

This is server log after changing try-catch block to this:

 try {
        System.out.println("
Trying to save..");
        JsonObject jsonObject = (JsonObject) parser.parse(request.getReader());
        System.out.println(jsonObject.get("login").toString()); //event this doesnt print

    } catch (IOException e) { // doesnt throw exception
        e.printStackTrace();
    }

@EDIT 3!!!!

I figured out that this line is cousing the errors showed in the second server log:

JsonObject jsonObject = (JsonObject) parser.parse(request.getReader());

What's wrong with that?

@EDIT 4

This is my current code for reading the json:

try {
            System.out.println("
Trying to save...");
            InputStream inputStream = request.getInputStream();
            JsonReader reader = Json.createReader(inputStream); //this is were error is 
            reader.close();
//            JsonObject jsonObject = reader.readObject();
//            reader.close();
//            System.out.println(jsonObject.get("login").toString()); 
////            uM.setLogin(jsonObject.get("login").toString());
//            uM.setPassword(jsonObject.get("password").toString());
//            System.out.println(uM.toString()); 
//            userDAO.save(uM);
        } catch (IOException e) { 
            e.printStackTrace();
        }

And this is current server log:
