Haohui Mai commented on HADOOP-11267:
-------------------------------------
+ try {
+ assertFalse(SecurityUtil.isTGSPrincipal
+ (new KerberosPrincipal("/@")));
+ } catch (IllegalArgumentException iae) {
+ // Same as above. In recent JDK versions, an IllegalArgumentException
+ // is thrown if the principal name is empty.
+ GenericTestUtils.assertExceptionContains("Empty nameString not allowed",
iae);
+ }
Maybe it makes more sense to remove the assertions instead of catching the
Exception as the check does not offer much value.
> TestSecurityUtil fails when run with JDK8 because of empty principal names
