This module abuses the JMX classes from a Java Applet to run arbitrary Java code  
outside of the sandbox as exploited in the wild in February of 2013. Additionally,  
this module bypasses default security settings introduced in Java 7 Update 10 to run  
unsigned applet without displaying any warning to the user.
