In that case new files are not owned by the user but instead by BUILTIN\ADMINISTRATORS. This breaks the assumptions of the test's whoami check. My suggestion is to cater for this case and don't fail the test but write a warning message to stdout that a whoami check is not correctly possible.

test/jdk/java/lang/ProcessHandle/InfoTest.java line 304:

Is there an alternative way to determine the expected username? 
Perhaps by running a windows command or extracting it from the environment (System.getEnv("XX"))?
