Eclipse vs. Unity: Global Menu not supported? (12.04)

Hi there,
today I decided to setup Eclipse Scala environment on my laptop... I usually work with Aptana but the project I'm currently involved in is based on Scala and I've been told to "dig deep".
So: let's go with customizations!

My perspective is ready, web extensions installed, Solarized theme loaded (well, not as good as Aptana's one)... but... oh my god! Global menu is not working? Why Eclipse's menu is shown below unity bar?!?

After a quick G search I came here : Eclipse is blacklisted from Unity Global menu

So, waiting for Canonical developers solving this issue, here's a simple work around: Hack #46

But seems like it's quite different on my Ubuntu (12.04) so, here's how it worked for me:

1. sudo vim /usr/lib/x86_64-linux-gnu/gtk-2.0/2.10.0/menuproxies/libappmenu.so
2. /Eclipse <return>
3. move to 'E' of Eclipse, type 'i' and then replace 'E' with 'X'
4. <esc> ':w' <return> ':q' <return>
5. sudo ldconfig
6. start Eclipse

Thanks to Vasile Rotaru for this hack, I've just adapted it to my Ubuntu 12.04 (64) and added some Vim's commands explications.

Bye,
Pietro
