I didn't get time to look at this yesterday.
I think the problem is (sort of) in SunGraphics2D.setComposite() where
we have
}

newCompType == CompositeType.Src ||
newCompType
This fixes it, although the same may need to be done to OGL and D3D

Why is SRC with an extra alpha handled any differently than SrcNoEa with
a color that has alpha? The two cases are supposed to be folded
together because it doesn't matter where the alpha comes from.
There is also a paintType indicator that indicates when the paint is
opaque. If you only
If you allow ALPHACOLOR (paintState = ALPHACOLOR) then you should be
able to handle Src with EA...

And the garbage problem is due to a bug in surfacedata where that

Hi,
While playing arround with the SRC composition rule I found what seems
to be a bug.
When rendering text with an AlphaComposite(SRC, EA) I get garbage when
enabling subpixel antialising:
g2d.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC, 0.01f));
Hi Clemens.
It's interesting to note that this doesn't happen on OpenJDK, and
on closed java the subpixel hint is not necessary to reproduce this.
Simply using VALUE_ANTIALIAS_ON and the SRC composite is enough.

Denis.

I have to enable lcd text antialising to get the described result,
however I see it
This is getting a bit puzzling .. what I see sounds more like what
Denis is seeing.
Are you using the X11 pipeline or Xrender ? I'm using X11.
