Hi;
I am using twitter4j-core-2.1.2.jar.
Following is my code which executed after callback url hit.
Code
String token = (String) session.getAttribute("token");
String tokenSecret = (String)session.getAttribute("tokenSecret");
AccessToken accessToken = new AccessToken(token, tokenSecret);
Twitter twitter = new
TwitterFactory().getOAuthAuthorizedInstance(CONSUMER_KEY,CONSUMER_SECRET,accessToken);
// getting exception on this line.
User user = twitter.verifyCredentials();
Follwowing is the exception
java.lang.IncompatibleClassChangeError: Found interface twitter4j.User, but class was expected
