The Java Card RE context does not have an AID. If an applet calls the getPreviousContextAID method when the context of the applet was entered directly from the Java Card RE context, this method returns null.
If the applet calls getPreviousContextAID from a method that may be accessed either from within the applet itself or when accessed via a shareable interface from an external applet, it shall check for null return before performing caller AID authentication.
