Push request: 7029903 Splash screen is not shown in 64-bit Linux with 16-bit color depth

[David Buck]

Hi!

This is a request to backport a jdk8 fix into jdk7u2.

CR:7029903 Splash screen is not shown in 64-bit Linux with 16-bit color 
depth

Weblink: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=2208636
(for some reason, the URL for the parent bug is not working. Sub CR (I 
believe that 2208636 will have all needed information.)

Description:
On X11, if image data for splash screen is small enough, it can
remain in the Xlib client buffer until the JVM starts up and starts
updating the GUI. I added an explicit call to Xflush() immediately
after the splash screen image is updated.

This is a regression introduced by the fix for cr6557810.


The fix is already included in jdk8 as:

     7029903: Splash screen is not shown in 64-bit Linux with 16-bit 
color depth
     Summary: Added Xflush() call after splash screen is updated to 
ensure update is no stuck in client side buffer until JVM starts up. See 
JET review request 4154 for details.

Original jdk code review was done with JET (inernal Oracle code review 
tool. Will use correct review procedure from now on.).

The patch for jdk7u2 is identical to the one in jdk8.
