[OpenJDK 2D-Dev] Fonts with embedded bitmaps are not always rotated(this bug is NOT fixed in Java8 yet?)

[Ayase177]

Hi 

I found the bug "Fonts with embedded bitmaps are not always rotated" in
Java8.
It seems that this bug is fixed for Java11.
(https://bugs.openjdk.java.net/browse/JDK-8204929)
There was the issue on this bug in Java8. 
But it is closed as duplicated.
(https://bugs.openjdk.java.net/browse/JDK-8163278) and
(https://bugs.openjdk.java.net/browse/JDK-8225334)
But,now this bug is NOT fixed in Java8 yet.
Rotation does not work properly with double-byte character sets.

Font size 24 over is OK.
Font size 21 under is NG.

I found two ways to workaround it.

1. Use SetRenderingHints and set VALUE_ANTIALIAS_ON
or
2.Use SetRenderingHints and set VALUE_FRACTIONALMETRICS_ON

Why this workaround works?
I would like some advice on whether this workaround is correct.
