I have issues with anti-aliased text rendering to translucent BufferedImage. Only \
anti-aliasing is rendered. Will this be fixed in Java8u60?

Pseudo code
BufferedImage - INT_ARGB
clear: new Color(255, 255, 255, 0)

g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, \
RenderingHints.VALUE_ANTIALIAS_ON); //  - independent on this setting \
g2.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING, \
RenderingHints.VALUE_TEXT_ANTIALIAS_DEFAULT);


g2.setComposite(AlphaComposite.SrcOver);
g2.setColor(Color.BLACK);

g2.drawGlyphVector OR g2.drawString

--
Java 8u45 Intel 64bit - linux

Look like     JDK-8013564 - Font rendering anti-aliasing in translucent \
BufferedImages broken  https://bugs.openjdk.java.net/browse/JDK-8013564

There is not very good workaround - fill glyph outline

Thank you
   Martin
