 * @test
 * @bug 4702543
 * @summary X500Principal encodes EmailAddress incorrectly -
 *
 *      fix has compatibility ramifications for policy.
 *
 *      this test is related to the Alias.java test in the same directory.
 *      the email address encoding in EmailAddress.policy is the one
 *      taken from the persistent certificate stored in Alias.keystore,
 *      and which has the incorrect encoding.  the alias is 'duke',
 *      and the DN is:  "emailaddress=duke@sun".  the cert was generated
 *      by a 1.4 JDK, so it has the wrong encoding for "duke@sun"
 *      (UTF-8 string instead of IA5String, i believe).
 *
 *      administrators would have placed an incorrectly encoded DN entry
 *      like this in their policies.  the fix for the above bug
 *      would have broken their policy because the incorrect
 *      encoding would be compared to a properly encoded DN from
 *      the current call thread.  if you run this test without
 *      a fix for the compatibility issue, the debug output will
 *      show the differences in the encodings.
 *
 *      so in addition to fixing the encoding,
 *      the policy implementation was updated to read the
 *      incorrectly encoded DN strings, generate new X500Principals,
 *      and dump out new DN strings that had the correct encoding.
 *      thus access control checks would no longer fail.
 *
