AppletContex.getApplets returns an enumeration of all the Applets
running on the page, including yourself.  

It works correctly when there are 1 to 11 instances of the Applet.

When you have 12+, the enumeration contains only 1 element, namely
yourself.  You can't see any of the other Applets.

Firefox, Opera, IE all behave this way.  Chrome works for n=12. I have
not done experiments for larger numbers.

I think what is happening is 12 or above, Firefox gives each Applet
not only a separate thread, but a separate JVM. Another symptom is the
appearance of multiple consoles at 12+

Either a browser should put all Applets of the same class in the same
JVM, or give you a way to force that.

Oracle, if they do anything, may just add a warning the documentation
for getApplets that it does not work for values of n+, where n is
determined by experiment.

Bugs like this give much more grief that my own bugs.  I expect the
system stuff to work as advertised, and keep looking for something
wrong it my own code, and only as a last resort start exploring the
possibility Oracle erred.
