Avoiding using Thread.sleep() when working with SqsListener

Question

I have SQS listener, and under a certain condition, I need to wait 120 seconds before executing method1(). But as I know SQS listener works multithreaded. Is there a way to avoid using Thread.sleep() to reuse the thread rather than leave it waiting? Here is listener code:

 @SqsListener(value = "${test}", deletionPolicy = SqsMessageDeletionPolicy.ON_SUCCESS)
public void listenTransactionEvent(@Payload SQSEvent sqsEvent) {
    String sqsPlainMessage = sqsEvent.getMessage();
    if (sqsPlainMessage.equals("test")) {
        Thread.sleep(120 * 1000L);
        method1();
    } else {
        method2();
    }
}

and configuration:

@Bean
public QueueMessageHandlerFactory queueMessageHandlerFactory(
        final ObjectMapper mapper,
        final AmazonSQSAsync amazonSQSAsync
) {
    final QueueMessageHandlerFactory queueHandlerFactory = new QueueMessageHandlerFactory();
    queueHandlerFactory.setAmazonSqs(amazonSQSAsync);
    queueHandlerFactory.setArgumentResolvers(Collections.singletonList(
            new PayloadMethodArgumentResolver(jackson2MessageConverter(mapper))
    ));
    return queueHandlerFactory;
}

I believe you may be looking for java.util.Timer to schedule a TimeTask or even using a java.util.concurrent.Future could release the thread calling listenTransactionEvent, but the waiting will just change place, sometimes depending on context Thread.sleep might be an acceptable solution.

Best regards.
