			This module exploits a vulnerability in Java Runtime Environment
			that allows an attacker to escape the Java Sandbox. By injecting
			a parameter into a javaws call within the BasicServiceImpl class
			the default java sandbox policy file can be therefore overwritten.
			The vulnerability affects version 6 prior to update 22.

			NOTE: Exploiting this vulnerability causes several sinister-looking
			popup windows saying that Java is "Downloading application."
