Loading FontManager from sun.font.fontmanager property

[Alexander Scherbatiy]

Hello,

There are two fixes which avoid using reflection during 
GraphicsEnvironment and Toolkit platform specific classes loading [1], [2]:
   8130266 Change the mechanism by which JDK loads the platform-specific 
GraphicsEnvironment class
   8212700 Change the mechanism by which JDK loads the platform-specific 
AWT Toolkit


The FontManagerFactory class still uses reflection to load platform 
specific FontManager class from "sun.font.fontmanager" property.

Should the "sun.font.fontmanager" property be removed in the same way as 
for GraphicsEnvironment and Toolkit properties and make FontManger 
loading from corresponding PlatformInfo classes?
