      We see the memory leak with the RemoteConnectionChannel.java when we try to use the JBOSS mbean server connection in web application.

      We initialize the JMX connection factory as below

        try {
                  this.jmxConnector = JMXConnectorFactory.connect(serviceURL, auth);
                  if (this.jmxConnector != null) {
                   
                      MBeanServerConnection mbs = this.jmxConnector.getMBeanServerConnection();
                      if (mbs != null) {
                          this.mbs = mbs;
                      }
                  }
                  
              } catch (IOException e) {
                  connected = false;
                  
                  
              }
      
      

      Then use mbean server connection after scheduled interval say 60 secs to read the mbeans from above mbean server connection.

        private Map<String, Object> getAttributesForMBean(ObjectName objectName, List<String> attributeNames) {
          	 
               HashMap<String, Object> attributeMap = new HashMap<String, Object>();
              for (String attributeName : attributeNames) {
                  Object attributeValue = null;
                  if (this.hasAttribute(objectName, attributeName)) {
                      try {
                          attributeValue = this.mbs.getAttribute(objectName, attributeName);
                      } catch (Exception e) {
                          logger.warn("In getAttributes(), for " + objectName + ": " , e);
                      }
                  }
                  attributeMap.put(attributeName, attributeValue);
              }
              
              return attributeMap;
          }
      
      

      We see that RemoteConnectionChannel keeps accumulating XnioWorkerTaskPool and leads to memory leak.
