Nitpick: is this line necessary?

test/jdk/javax/swing/JList/bug4618767.java line 55:

Do you think it might be better to initialise it directly on line 52? 


private static CountDownLatch listGainedFocusLatch = new CountDownLatch(1);

test/jdk/javax/swing/JList/bug4618767.java line 86:

Do you think it might be easier to read if this is initialised on line 49?


private static final JList list = new JList(new String[] {"one", "two", "three", "four"});


and the same for line 69 `f = new JFrame("bug4618767");` 

I feel it is going to be easier to read if global variables were initialised at class level when possible, especially if they are not reassigned further. This way they can also be finalised. But if you feel it's ok as it is, I'm fine with it.
