(api) Backwards compatibility of java.applet.AppletContext

-----------------------------------------------------------------------------

Note - this is an *interface*, not a class as mentioned originally. Adding
the methods to a public interface breaks every class that implements
the interface.

These methods were added to the java.applet.AppletContext interface:

    setStream(), getStream(), getStreamKeys()

This completely breaks backwards compatibility. This interface has existed since JDK1.0.

This causes the Java(TM) Accessibility Helper (a Sun product) to fail under JRE1.4. The helper is used to test applets, and implements AppletContext
for that purpose.
