I have a JSON string which is coming from Queue. I need to send it as request parameter to create a case in BPM via REST. Rest Service Input- request(String) Therefore I form the below and try to call the rest service

    Request- {\"request\":\"{'hits' : [{'id' : '50', 'version' : 1}]}\"}

When i use the uri="https://localhost:9044/rest/bpm/wle/v1/service/RISKM%40CreateCase?action=start&params=%7B%22request%22%3A%22%7B+%5C%22hits%5C%22+%3A+%5B+%7B+%5C%22id%5C%22+%3A+%5C%2250%5C%22%2C+%5C%22version%5C%22+%3A+1%7D%5D%7D%22%7D&createTask=false&parts=all";

Above works fine

but when i use the below

uri="https://localhost:9044/rest/bpm/wle/v1/service/RISKM@CreateCase?action=start&createTask=false&parts=all&params={\"request\":\"{'hits' : [{'id' : '50', 'version' : 1}]}\"}";

It gives the error:- Error----HTTP Version Not Supported

java.lang.NullPointerException
Response 500

    at com.sita.createCase.Restcall2.main(Restcall2.java:216)

If i copy the same url in postman it work fine in both the case. Need help on how can i send this request from Java Client. Also how to stringify the json string?

Below is the Java Client Code

       HttpsURLConnection connection = null;
            try {
            URL url = new URL(uri);
            connection = (HttpsURLConnection) url.openConnection();
            connection.setRequestMethod("POST");    
            connection.setRequestProperty("Authorization", authorization);
            connection.connect();
        }

you must Send Every Parameters as A Single Parameter. Can't Send An Object As A Parameter In Address. If You Want To Send An Object, Must Send It As A Body. In This Case You Should Write:

id=50&version=1

instead Of :

params={"request":"{'hits' : [{'id' : '50', 'version' : 1}]}"}"

And Handle Validation Of Objects In Backend.
