    Description

      What are the steps to reproduce your problem?

      Just try that:

      public static void main(String[] args) throws InterruptedException {
    ExternalTaskClient client = ExternalTaskClient.create()
        .baseUrl("http://localhost:8080/engine-rest")
        .asyncResponseTimeout(1000)
        .build();

    Thread.sleep(300_000);
}

      What is the problem?

      CPU usage goes to 100% (for one thread).

      What would be the expected behavior:

      Keep calm and wait for subscription.
