stream was reset: PROTOCOL_ERROR on using http2.0

[sinhaashish]

I am using minio for Object storage. Minio is a golang project using go1.12 as the base go version.
The server is HTTP2 enabled. I use using minio java client which uses okhttp3 . when i try to store the object in a bucket in multi threaded mode i get okhttp3.internal.http2.StreamResetException: stream was reset: NO_ERROR.
Refer minio/minio#7501 .

okhttp3.OkHttpClient uses http2.0 by default which causes such issue.
If i forcefully set the protocol to 1.1 ,it works fine.
Refer PR #766.

Issue raised for go-upstream
and okhhtp

Below is the code which replicates the problem

import io.minio.MinioClient;
class PutObjectRunnable implements Runnable {
   MinioClient client;
   String bucketName;
   String filename;

   public PutObjectRunnable(MinioClient client, String bucketName, String filename) {
       this.client = client;
       this.bucketName = bucketName;
       this.filename = filename;
   }

   public void run() {
       StringBuffer traceBuffer = new StringBuffer();

       try {

           client.putObject(bucketName, filename, filename);

       } catch (Exception e) {
           System.err.print(traceBuffer.toString());
           e.printStackTrace();
       }
   }
}

public class ThreadedPutObject {
    public static void main(String args[]) throws Exception {
	try{
        MinioClient client = new MinioClient("https://play.min.io:9000", "Q3AM3UQ867SPQQA43P2F", "zuf+tfteSlswRu7BJ86wekitnifILbZam1KYY3TG", true);
        client.traceOn(System.out);
        long startTime = System.currentTimeMillis();
		 boolean found = minioClient.bucketExists("my-bucketname");
      if (found) {
        System.out.println("my-bucketname already exists");
      } else {
        // Create bucket 'my-bucketname'.
        minioClient.makeBucket("my-bucketname");
        System.out.println("my-bucketname is created successfully");
      }        
      Thread[] threads = new Thread[7];
      String[] location = new String[]{"<<PATH_TO_OBJECT_1>>",
                                       "<<PATH_TO_OBJECT_2>>",

      for (int i = 0; i < 7; i++) {
            PutObjectRunnable pr = new PutObjectRunnable(client, "my-bucketname",location[i] );
          threads[i] = new Thread(pr);
      }
      for (int i = 0; i < 7; i++) {
        threads[i].start();
      }
            // Waiting for threads to complete.
      for (int i = 0; i < 7; i++) {
         threads[i].join();
          System.out.println(i);
        }
        // All threads are completed.
        } catch (Exception e) {
