--------------------------------------------------------------------------------------

                 Key: JBAS-4150
                 URL: http://jira.jboss.com/jira/browse/JBAS-4150
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
            Reporter: Nikolay Chugunov


ClassCastException thrown when receiving serviceNames attribute of Catalina:type=Server mbean.

To reproduce start JBoss AS server with jmx connector as described at http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossMBeansInJConsole
Run following test:

import javax.management.*;
import javax.management.remote.*;

public class CatalinaMBeanTest {
	public static void main(final String[] args) throws Exception {
		final JMXServiceURL url = new JMXServiceURL(
				"service:jmx:rmi:///jndi/rmi://127.0.0.1:1099/jmxrmi");
		final MBeanServerConnection conncetion = JMXConnectorFactory.connect(
				url, null).getMBeanServerConnection();
		conncetion.getAttribute(new ObjectName("Catalina:type=Server"),
				"serviceNames");
	}
}

Output:
