Actually, there might be a way to get just what the OP is after.

First, as has been said to the OP numerous times in this thread, dump
that code that has a HIDE_ON_CLOSE in the windowClosing event.  It's
useless.  You're not understanding the difference between hiding a
window and hiding an application.  Simply call the JFrame's
setDefaultCloseOperation(HIDE_ON_CLOSE) to have it automatically hide
when its close decoration is activated.  There's no logical need to even
have a window listener involved if that's all you're attempting to do.

<http://developer.apple.com/documentation/Java/Reference/1.4.2/appledoc/a
pi/index.html> leads to Apple's API docs on Mac-specific extensions to
1.4.2.  Look at the Application class and the ApplicationListener
interface.  When the latter's handleReOpenApplication() method is
called, it's supposed to signal that a user has clicked the dock icon
for the application.  It can also get triggered if another application
generates an open request (say on a type of file you handle) to your
application.  This might well be the ideal spot to determine whether the
app's primary JFrame is visible and to make it visible if not.  And of
course it's got the hooks for responding to the About and Quit menu
items that are inherent in all OS X applications, among other things.
