RULE javax/swing/JRadioButton/8033699/bug8033699.java Exception java.lang.RuntimeException: Focus is not on Radio Button Single as Expected

Tested and failed many times on OS X 10.9 with jdk9 client PIT destined to approximately b40. The test is already in the repository. I changed it for JDK-8063107 but it fails just the same before and after my change.
