A little JMX Server inspection tool. This JSP allows you to list all attributes on all mbeans
in all mbean servers in your JVM. We make a reasonable attempt to also print the value of each
attribute,although we don't dig into the more complex structures. JConsole is a much better
tool for that.
And yes,the resulting list is *huge*. :-)
