xmlaccountsparser#error] Invalid GUID in accounts XML: 'admin'; badly formed hexadecimal UUID string <-- the bold font part shows up when I print the exception.

The conf/auth/accounts-test.xml has:
<accounts realm="Test Realm">
  <user>
    <uid>admin</uid>
    <guid>admin</guid>
    <password>admin</password>
    <name>Super User</name>
    <first-name>Super</first-name>
    <last-name>User</last-name>
  </user>

Any ideas,
thanks,
Ravi.
