Review comment:
       LocatorLauncherWithPulseAcceptanceTest is the only test in this PR that doesn't provide a custom log4j2 xml file. So that means, it'll create a locator log file.
   
   The others tests all use a custom log4j2 xml file which turns off logging to a file and turns on logging to stdout. These tests assert that the locator log file doesn't exist to help verify that the custom log4j2 xml file for that test was actually used.
