Tested with Ubuntu 14.04, Eclipse Kepler SR2
Eclipse itself works fine but menus File, Edit etc. does not open and cut off.
To fix this, open eclipse.desktop file for edit. It's located at
~/.local/share/applications/eclipse.desktop
or at /usr/share/applications/eclipse.desktop
Find the line Exec=… and replace the whole line with
Exec = env UBUNTU_MENUPROXY = /opt/eclipse/eclipse
replace /opt/eclipse/eclipse with a path to your Eclipse.
