Cannot login to JIRA using JIRA REST Java client JRJC

[HiteshS]

We are using Jira rest client sdk(jira-rest-java-client-api-2.0.0-m31.jar and jira-rest-java-client-core-2.0.0-m31.jar) for login and fetching data from Jira as follows:

package com.jira;

import java.net.URI;

import com.atlassian.jira.rest.client.api.JiraRestClient;
import com.atlassian.jira.rest.client.api.domain.Session;
import com.atlassian.jira.rest.client.internal.async.AsynchronousJiraRestClientFactory;

public class JiraLogin {
                private static final AsynchronousJiraRestClientFactory FACTORY = new AsynchronousJiraRestClientFactory();
                
                public static void main(String args[]){
                                String url = "https://mycompany.atlassian.net";
                                String username = "user";
                                String email = "user@xyzcompany.com";
                                String password = "xxxxx";
                                
                                try {
                                                URI serverURI = new URI(url);
                                                JiraRestClient jrc = FACTORY.createWithBasicHttpAuthentication(serverURI, email, password);
                                                Session s = jrc.getSessionClient().getCurrentSession().claim();
                                                username = s.getUsername();
                                                System.out.println("User '" + username + "' logged in successfully.");
                                } catch (Exception e) {
                                                e.printStackTrace();
                                }
                }
}

Till friday morning, we were able to login to Jira using the code mentioned above. Now, it has started giving below error/exception when we try to login using the same sdk:

Looks like something has changed on JIRA server side. Can someone fix it? Or any alternatives for the login?
