[Permission Target Name] listenToAllAWTEvents After adding an AWT event listener malicious code may scan all AWT events dispatched in the system allowing it to read all user input (such as passwords). Each AWT event listener is called from within the context of that event queue's EventDispatchThread so if the accessEventQueue permission is also enabled malicious code could modify the contents of AWT event queues system-wide causing the application or applet to misbehave in an insecure manner. [What the Permission Allows] 
Listen to all AWT events system-wide
