Unable to create new connections per iteration- websocket sampler

[shwetahooda]

Hi,
I have a scenario where a user makes websocket connection to an application and continues receiving messages. When a user sends a particular message, the connection gets closed. This works fine for one iteration.
However, when the user attempts second iteration, it is not able to open a new connection and can't even reopen the existing connection.

[Problems]

• Unexpected error: RemoteEndpoint unavailable, current state [CLOSED], expecting [OPEN or CONNECTED]

  I am using JMeter 3.1

Has anyone else observed this issue with Websocket Sampler?

Appreciate any help.

Thanks

fix case:
//import java.util.LinkedList;
import java.util.concurrent.ConcurrentLinkedQueue;

//protected Deque responeBacklog = new LinkedList();
Queue responeBacklog = new ConcurrentLinkedQueue();

test OK!!
