JavaFX app with Spring doesn't terminate on Mac OS X with Cmd-Q

I have a JavaFX app that uses Spring to instantiate a number of services
and presentation controllers. I think it's relevant to mention that among
other services there's Jetty, an embedded web server that starts listening
to a socket with its own threads. The Spring ApplicationContext is
initialized in background after init() is called; and it also uses
applicationContext.registerShutdownHook(). When I run the application in
development mode (with Maven, from the terminal) or I launch the Java stub
inside the bundled .app from the terminal (so the process is bound to the
terminal) and I hit Ctrl-C, the application properly quits (with the
Spring Application Context properly shutting down everything). When I
launch the bundled .app and I press Cmd-Q, the window closes, but the
application lingers somewhere (e.g. I see it in running processes). I have
to "force quit" it. Platform.setImplicitExit(true) doesn't make any
I expected that Cmd-Q called System.exit() and the Spring
ApplicationContext just had its opportunity to orderly quit thanks to the
shutdown hook. Instead, I see that the ApplicationContext stays alive and
probably the threads started by some services keep the application running.
I've found that this solution works:
public void handle (final @Nonnull WindowEvent event)
For me it's fine, but I'd like to understand whether this is the correct
behaviour, or I'm doing something wrong, or there's a bug somewhere.
Details: JDK 1.7.0_25 with its embedded JavaFX runtime, Mac OS X 10.8.4.
