<Swing Dev> Bug in JLabel setForeground JDK 1.8.0_31

[Alexander Scherbatiy]

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.
