    Since this method is setting system properties I don't think it is appropriate to have it in LocatorTestBase.  You should move it to AutoConnectionSourceDUnitTest and use the DistributedRestoreSystemProperties rule to ensure that the properties are cleaned up.  To do that, add this to AutoConnectionSourceDUnitTest:
    
      @Rule
      public DistributedRestoreSystemProperties restoreSystemProperties =
          new DistributedRestoreSystemProperties();

> If you connect to a Geode cluster using a locator from the client, the locator list request will be executed at regular intervals in the background thread. I want to tune this interval. I understand that this interval can be changed by the ping-interval of the Pool attribute. However, I think that ping-interval originally sets the ping interval for health check to the cache server. Therefore, it is not possible to change the locator list request interval without changing the health check interval to the cache server. So,I want to add a java system property that can change the locator list request interval.
> The locator list request interval is determined by the following priority order.
>   1. java system property "gemfire.LOCATOR_UPDATE_INTERVAL"
>   2. ping-interval of the Pool attribute
> In addition, when changing this time, the background thread is activated only when this value is a positive value.
