Makes sense… However, a generic title would be good enough. Something like _“Radio button focus tests”_. The current title is too long, it doesn't fit in the title bar of the frame (at least on Windows), therefore I see no point in making it comprehensive and long.

In majority of cases, I do too. Yet I tend not to change lines that I don't touch. From this point of view, additional changes aren't necessary — none of the lines that don't fit into 80-column limit aren't touched.

The problem I see with additional refactoring is that it adds noise to the code review and it makes it harder to understand what the real, important changes are.

Use *your common sense*.

> Please limit to 80 cols wherever applicable

This is not applied strictly… I'm for following the 80-column limit where it doesn't reduce the readability. Yet I'm for stronger enforcement of 100-column limit. There are quite a few lines which are longer than 100 columns. The culprit is `KeyboardFocusManager.getCurrentKeyboardFocusManager().getFocusOwner()` which accounts for 70 characters.

I'd like to make it shorter, and the focus manager can be cached after the first usage. At the same time, I'm unsure doing so in this code review is reasonable.
