Please review the fix for jdk11:

bug: https://bugs.openjdk.java.net/browse/JDK-8201240
webrev: http://cr.openjdk.java.net/~aivanov/8201240/jdk11/webrev.00/

BufImgSurfaceData.ICMColorData uses finalize() to dispose of native 

2D components usually use Java 2D Disposer. It can be used here too, and 
the now deprecated finalize() can be removed consequently.

I ran SwingSet2 and Java2Demo.
When BufImgSurfaceData.ICMColorData objects become unreachable, 
BufImg_Dispose_ICMColorData gets called and the associated native 
resources are freed.

Thank you in advance.
