This bug happen under solaris only, under windows it works fine.

Attach is a test program KeyEventBug2.java
which contains a Java3D Canvas3D
and a JButton inside JPanel.

when the program initialize, keyListener is added in
canvas3D.addKeyListener( this );
(Note that Canvas3D did not overwrite addKeyListener())

As expect, after the program run, press any key will
receive key event as output by the program.
However after the JButton "Test" is pressed ( which
did nothing since there is no ActionListener register to it),
and we move the mouse back to Canvas3D, click it (
try to make it get focus), there is no more KeyEvent
received.

To workaround this, we have to explicitly add the
mouseListener to Canvas3D, then detect mouseEntered()
and called canvas3D.requestFocus(). Try to
uncomment the line
// canvas3D.addMouseListener( this );

 In this way
we can get back the focus. Under windows, there is
no need to do this.

However this cause
Undesired "bring to front" window on mouseEnter under window
as complain by customer (see 4354276)

To work around, we have to explicitly detect whether this
is under window or solaris (not cross platform anymore),
if it is under solaris, need to explicitly requestFocus()
in mouseEntered().

To reproduce this problem, please put the four jar files
under your lib/ext directory and the two .so files
under your bin/sparc directory. Then run
