Description
Issue:
Java's Native IM status window is not displayed even if it's there.
Because of this issue, user cannot get proper visual feedback during key 
input operation.
We found this issue on Tiger VNC.

Reason:
Java may pick up unexpected visual for Java's Native IM status window 
when  Xserver supports multiple visual.

Workaround:
X11 default visual can be changed by FORCEDEFVIS environment variable, 
but it's not easy to find out default visual id.

I used kinput2 XIM server to take screen shot.

Fix Request This fix is required Linux's X11 Input Method and VNC environment. I'd like to request the fix in 11u. The patch could apply cleanly. * src/java.desktop/unix/native/libawt_xawt/awt/awt_GraphicsEnv.c * src/java.desktop/unix/native/libawt_xawt/awt/awt_InputMethod.c (But copyright year was not updated, because of prerequisite 8214076 for awt_GraphicsEnv.c)
