/* @test

 * @summary Test the internal NameService implementation which is enabled via
 *          the system property jdk.net.hosts.file. This property specifies
 *          a file name that contains address host mappings, similar to those in
 *          /etc/hosts file. TestHosts-II file doesn't exist, so a UHE should be
 *          thrown
