Spring Sleuth | Create fresh new (detached/orphaned) Trace

I got a Spring Boot application making use of Spring Sleuth for tracing inter-service calls. Within that application a ScheduledExecutorService exists that performs http requests in a loop (pseudo-code below):

class HttpCaller implements Runnable {
  public void run() {
    performHttpCall();
    // "loop"
    executor.submit(this::run);
  }
}

// start it once
scheduler.submit(new HttpCaller());

If I now have a look at the traces produced by Sleuth and stored in Zipkin I can see that all http calls are associated to a single Trace. Most likely because the trace context is handed over during the call to ScheduledExecutorService::submit.

How can I clear the current trace before starting the next iteration so that each http call will result in a new detached/orphaned trace?

If you're using Sleuth 2.0 you can call on the Tracer a method to create a new trace. In the older version of sleuth I guess what I'd do is to use an executor that is NOT a bean. That way you would lose the trace and it would get restarted at some point (by rest template or sth like that).
