odd AWT focus bug in JDK 1.1 and JDK 1.2 (with test case)

[Nelson Minar]

/** Demonstration of a bug in focus with the AWT on Linux and Java.
 **
 ** Creates a Frame with a Choice and a TextArea. Every other time the
 ** Choice box is selected, the text area loses the ability to take
 ** focus. To demonstrate this, type some text into the text area,
 ** then select something from the Choice. Type into the text area
 ** again, then select something from the Choice again. The text area
 ** is now locked, and cannot be typed into.
 **
 ** Removing focus and restoring it to the Java app allows the text
 ** area to be used again, but it re-locks every second time the
 ** Choice is selected.
 **
 ** Bug verified with WindowMaker and fvwm2,
 ** Blackdown JDK 1.1.7_v3 and 1.2_pre2
