Here is the solution

JMXServiceURL url = new JMXServiceURL("service:jmx:rmi://0.0.0.0:44444/jndi/rmi://0.0.0.0:1099/karaf-root");

HashMap<String, String[]> environment = new HashMap<String, String[]>();
String[] creds = { "admin", "admin" };
environment.put(JMXConnector.CREDENTIALS, creds);

JMXConnector jmxc = JMXConnectorFactory.connect(url, environment);
MBeanServerConnection connection = jmxc.getMBeanServerConnection();

You are missing required credentials.

Looking at this tutorial you need to provide credentials to the JMXConnectorFactory

Map env = ...;
String[] creds = {"monitorRole", "mrpasswd"};
env.put(JMXConnector.CREDENTIALS, creds);
JMXConnector cc = JMXConnectorFactory.connect(url, env);
