Is it reproduced only on Linux?
It looks like a known bug 8054638 xrender: text drawn after
setColor(Color.white) is actually black
https://bugs.openjdk.java.net/browse/JDK-8054638
which should have been already fixed in JDK 8u40.
Thanks,
Alexandr.

Hi Support Team,
something seems to be wrong in the setForeground method of JLabel.
The following minimal example reproduces the error on my maschine.
As you can imagine a WHITE text is expected but as screenshot jdk8.png
shows it's actually black. After changing to jdk7 the same program
behaves like expected (see screenshot jdk7.png).
(Exact jdk versions see at the end of the e-mail)
public static void main(String[] args) throws Exception {
JFrame jframe = new JFrame();
jframe.setLayout(new FlowLayout());
JLabel test = new JLabel();
test.setText("This text should be white");
test.setForeground(Color.WHITE);
jframe.add(test);
jframe.pack();
jframe.setVisible(true);
System.out.println(test.getForeground());
}
