[TEST_BUG] Failure javax/swing/JRadioButton/FocusTraversal/FocusTraversal.java

This test consistently (12/12) fails on OS X 10.10 and also fails on Ubuntu 14.04. I didn't try more systems since the test flaw is obvious: it let's Robot to release button immediately after it is pressed. Sometimes it works but very rarely on OS X. The fix is simple:
