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. Reviewed-by: kevinw, anthony

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.

Cheers, -Buck
