Swing module's module-info file

[Nir Lisker]

Hi,

I didn't follow all the latest changes to the Swing module, but I notice
now its module-info.java file is not in the same place where other modules
have theirs:

It's under javafx.swing\src\main\module-info instead of
javafx.<other>\src\main\java.

Is there a reason for this?
