Unity HUD does not work with Java applications

[Sven Romeike]

The Unity HUD is not usable in Java applications. I tried to use the Unity Launcher in "Freemind" and "Freeplane" but none of them did show any menu items in the HUD.

reproduce:

1) start a Java application (in my case Freemind or Freeplane)
2) lookup a menuentry in the applications menus and remember the name
2) press Alt and try to search the menuentry you just looked up

expected result:
the menuentry should show up in the HUD

actual result:
the HUD does not work at all in Java applications

Thank you for your bug report, do you get the menus for those applications correctly exported in the unity panel menus?

[Sven Romeike (lun4tic)]

No, the menus appear very dark, the hud does not work and they dont integrate in the panel.

Java font rendering looks somehow awkward and not very smooth but at least it uses the correct theme.

I wanted to file each issue in a seperate bug like this one here:
https://bugs.launchpad.net/light-themes/+bug/932274 which seems to be connected to the light themes.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Bilal Akhtar (bilalakhtar)]

Since there's no common UI toolkit for Java apps, it's tough to be able to extract menus out of those, and proxy those over DBus.

In normal circumstances, the application developers themselves need to manually proxy the menus using dbusmenu.

I do not clearly remember if it worked before upgrade from 11.10 to 12.04, but I think YES. Greyed menu disablig me from use it and read menu quickly... so I would notice that in 11.10 if it would be there
