Bundle OpenJDK 11 with Flatpak

We currently use OpenJDK 10 which is deprecated. Switching to OpenJDK 11 is not possible at the moment because building fails with the following error:

Installing from GNOME is not an option because it bundles an older version:

@nicoalt Do you mind telling what exactly you did to get around this, as I face the exact same problem and running flatpak install --from https://flathub.org/repo/appstream/org.gnome.Builder.flatpakref as mentioned in https://code.briarproject.org/nicoalt/briar-gtk/commit/474a57bfab978fcbc29c49f3f344bc0940307b20 doesn't solve it for me.

@Deiseroth Yeah, this bug was really nasty.

I experienced the bug with both flatpak and gnome-builder installed from the official Arch Linux repositories. Then, I deleted gnome-builder via pacman -Rsnu and also deleted all related directories in ~/, ~/.local/ and ~/.config/. Finally, after installing gnome-builder with the mentioned flatpak install --from ... command, I had a completely fresh gnome-builder and everything worked, magically.

I'm not really happy with it, as I didn't understand why it worked, but now it does work. If it does not for you, do you mind opening an issue on upstream's repo and CC me there? I'm @altnico on GitHub.

@nicoalt I didn't try it exactly as you said, in particular I didn't install the gnome-builder from arch. However it shouldn't be necessary anyways. Maybe we better file a bug upstream anyways.
