consuming messages with REST API in Java

[Luigi Suardi]

hello activemq,

i am using amq 5.15.9 and want to consume messages using the REST API. i 
am hitting the issue described in the documentation @ 
https://activemq.apache.org/rest

"When consuming messages using the REST API, you have to keep session 
alive between GET requests, or you’ll create a separate consumer for 
every request and due to prefetch limit your succeeding call will hang."

I wrote my consumer in Java 8 using 
org.springframework.web.client.RestTemplate

        HttpHeaders headers = new HttpHeaders();
        headers.set("Authorization", getAuthorizationHeader());
        headers.set("Connection", "Keep-Alive");

        HttpEntity<String> request = new HttpEntity<String>("", headers);

        ResponseEntity<String> response =
            restTemplate.exchange(
"http://localhost:8161/api/message/quote?type=queue";,
                HttpMethod.GET,
                request,
                String.class);

and getting a successful consume on first request and hanging request 
from then on with 204 response after a long wait...

can someone please share an example of working Java consumer using the 
REST API? I does not matter if based on RestTemplate or other tool for 
HTTP client requests.

Thanks much in advance.
Luigi
