Java Swing Ayatana is a project that brings Ubuntu global menu (AppMenu) and HUD support for Java Swing applications.
JAyatana version 2 was released recently, getting support for Ubuntu 13.10 along with a PPA for easy installation. Update: the PPA now supports Ubuntu 14.04 and 14.10.
Using this, you'll get Unity AppMenu and HUD support for applications such as: NetBeans IDE, IntelliJ IDEA, Android Studio, jDownloader and so on.
Here's an IntelliJ IDEA screenshot using a global menu under Unity (Ubuntu 14.04):
And Netbeans IDE:
And of course, HUD works too:
Note that this won't work for Eclipse because it's a SWT application (update: in Ubuntu 14.04, Eclipse has HUD / AppMenu support by default). If you want Unity AppMenu / HUD support for Eclipse IDE, see the instructions HERE for Ubuntu 13.04 and older or, for Ubuntu 14.04, use the new unity-gtk-module dconf option to whitelist Eclipse. Unfortunately the old method to enable the Eclipse AppMenu doesn't work properly in Ubuntu 13.10.

If you want to checkout the source, report bugs and so on, see the Java Swing Ayatana page @ Google Code.
How to rever the changes
1. Because files in /etc/ are only removed when the package that installs them is purged, to revert the changes you'll have to purge the packages installed from the PPA using the following command:
sudo apt-get --purge remove jayatana libjayatana libjayatanaag libjayatana-java libjayatanaag-java
2. And finally, log out and log back in.
