Public bug reported:

I have a weird issue where an old app of mine which is written in
Eclipse RCP using SWT. It is an older Eclipse 3.x version.

I am running uptodate Ubuntu 19.10, on Ubuntu 18.4 LTS everything works
fine.

When i start the app after compiling it using the latest Eclipse
edition, then when i start the app, first i needed to install
libgtk2.0-0. Which i found out using ldd.

The app then doesn't start for quite a while. I can't see any errors
ore warnings anywhere. Maybe someone can point me in the right area?

Anyhow, searching the web i did find a solution: Either i start the
app as root, or using the following command:

    dbus-launch --exit-with-session java -jar MyApp.jar

But both are not very helpful as i can't start the app like this from
Eclipse to allow for debugging and modifying. And starting as root
isn't optimal either.

Has anyone got any idea on how i can fix this, or is this perhaps some
kind of bug?
