> Running {{TestSecurityUtil}} on JDK8 will fail:
> {code}
> java.lang.IllegalArgumentException: Empty nameString not allowed
> 	at sun.security.krb5.PrincipalName.validateNameStrings(PrincipalName.java:171)
> 	at sun.security.krb5.PrincipalName.<init>(PrincipalName.java:393)
> 	at sun.security.krb5.PrincipalName.<init>(PrincipalName.java:460)

> 	at org.apache.hadoop.security.TestSecurityUtil.isOriginalTGTReturnsCorrectValues(TestSecurityUtil.java:57)
> {code}
> In JDK8, PrincipalName checks that its name is not empty and throws an IllegalArgumentException if it is empty. This didn't happen in JDK6/7.
