[OpenJDK 2D-Dev] [7u6] request for review: 7120895: FontConfiguration should not use thread contextClassLoader

  could you please review a backport of the fix for 7120895 to 7u6?

  The problem there seems to be caused by an attempt to load
  sun.awt.HKSCS class using thread context classloader, that
  leads to loading lazy jars in case of webstart application,
  and has noticeable performance impact.

  The problem can be resolved by using system class loader instead
  of thread context class loader (FontConfiguration.
  getFontCharsetEncoder, lines 949 - 950).
  Note that we use this branch of code just to resolve "sun.awt.*"
  charset names, so we can limit the scope to search by system
  classes only.
