@Exported public class UnixNumericGroupPrincipal extends Object implements Principal, Serializable
 This class implements the Principal interface
 and represents a user's Unix group identification number (GID).
 
 Principals such as this UnixNumericGroupPrincipal
 may be associated with a particular Subject
 to augment that Subject with an additional
 identity.  Refer to the Subject class for more information
 on how to achieve this.  Authorization decisions can then be based upon
 the Principals associated with a Subject.
