NullPointerException while trying close consumer

I am getting random NullPointerException during runtime when i try to close the consumer. The issue happens when request rate is high, i used Jmeter to test the load. try-with causes response to be 500. i am using JMSContext.

@RestController
public class DummyController {

    @Autowired
    JMSContext context; //Bean is created and injected else where

    @GetMapping(value = "/test")
    String test() {
        Destination destination = context.createQueue("persistent://id-service/my.name.space/Java.AMQP.Test.Queue");
        TemporaryQueue replyToDestination = context.createTemporaryQueue();
        context.createProducer().setJMSReplyTo(replyToDestination).send(destination, "text 123");

        //Other Processing

        //Consumer for the result
        JMSConsumer consumer = context.createConsumer(replyToDestination);
        String message = consumer.receiveBody(String.class) + "<br>Producer Reply : " + replyToDestination;
        try {
            consumer.close();
        } catch (JMSRuntimeException ex) {
            ex.printStackTrace();
        }
        return message;
    }
}
