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

Have you tested that it works?

Start jboss, point to http://localhost:8080/web-console/, navigate to 'System', 'JMX MBeans', 'jboss.system', 'jboss.system:type=ServerInfo".

Right click on the 'FreeMemory' attribute and choose to create a graph. It hangs, with this StackTrace:
