How to ignore SSL certificate in custom JMX client

Vote count:

I want to write a custom JMX client. The client connects to a server I trust. I definitely don't want to import the key using the keytool. It fails when getting the connection with a SsLHandshakeException.

String username = "admin";
String password = "admin";
String[] credentials = new String[] { username, password };
Map<String, Object> env = new HashMap<>();
env.put(JMXConnector.CREDENTIALS, credentials);
// Only required for SSL Connections
env.put("com.sun.jndi.rmi.factory.socket", new SslRMIClientSocketFactory());
// MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://trustedhost:10010/jmxrmi");
JMXConnector jmxc = JMXConnectorFactory.connect(url, env);

The Exception I get:

Exception in thread "main" java.io.IOException: Failed to retrieve RMIServer stub: javax.naming.CommunicationException [Root exception is java.rmi.ConnectIOException: error during JRMP connection establishment; nested exception is:
