Comment 96 for bug 618587

This issue is definitely not an Eclipse one, but an Ubuntu one. Ubuntu hardcoded an exception for Eclipse menu in there menu manager.
This exception can be removed on the Ubuntu side by tweak linked earlier by Luis Fernando: https://bugs.launchpad.net/ubuntu/+source/libdbusmenu/+bug/618587/comments/46 It's working correctly as far as I've used Eclipse for the last few days.

Also note that Ubuntu menu are used for other RCP applications that are not titled "Eclipse".

For further better integration of Eclipse into Ubuntu, follow this Ubuntu ticket: https://bugs.launchpad.net/ubuntu/+source/appmenu-gtk/+bug/865389 and help it to get merged into Ubuntu.

If some error specific to Eclipse happen in Ubuntu after this ticket is fixed, or with already existing other RCP applications, then please open other tickets specific to these issues.
