I read it, but still think that this bug is another variation of 8142966, metrics returned
by both methods should be in sync, it means the JComponent.getFontMetrics should use the
same "default" AA hint, or the g.getFontMetrics() should use proper AA property
based on "awt.font.desktophints" and/or clientproperty.

I think the proper way to fix it is to change the Swing itself:
  - if the L&F support "awt.font.desktophints" then Swing should proper initialize the graphics of the JComponent
  - if the L&F ignore/unsupport "awt.font.desktophints" then JComponent.getFontMetrics() should ignore AA
