I get the below exception when trying to do a query for against the
contact service using 2 legged oauth.
java.lang.NullPointerException: No authentication header information

This is particularly odd, since right before the contact query
executes I can do a search against the documents API just fine and I
get back the list of documents for this user.
GoogleOAuthParameters oauthParameters = new GoogleOAuthParameters();
oauthParameters.setOAuthConsumerKey(<<private>>);
oauthParameters.setOAuthConsumerSecret(<<private>>);
ContactsService contactsService = new
ContactsService(APPLICATION_NAME);
contactsService.setOAuthCredentials(oauthParameters , new
OAuthHmacSha1Signer());
ContactQuery query = new ContactQuery (new URL("https://www.google.com/
m8/feeds/contacts/default/full")));
query.addCustomParameter(new CustomParameter("xoauth_requestor_id",
getCurrentUser().getEmail())); /
query.setFullTextQuery(search);
ContactFeed feed = contactsService.getFeed(query, ContactFeed.class);
Any help would be greatly appreciated.
