[Prasanta Sadhukhan]

> javax/swing/JRadioButton/4314194/bug4314194.java correct color pixels pixel % varies between 30% for Metal to about 20% for Nimbus to about 19% for Windows L&F. But Nimbus in linux correct color pixel % falls to about 14%
> so adjusted % tolerance check to 10
> Also, JDK-8075916 is fixed for NimbusL&F but same issue is present for GTK L&F which is to be addressed separately as JDK-8295006 so problemlisted for now
