bndtools debug bundle in equinox GUI

Question

I am converting a PDE plugin into a bnd bradle build. I have a runbnd file, see below, which resolves nicely to include all custom and external dependencies. If I click on either "Run OSGi" or "Debug OSGi" the bundle is somehow started as I can see from the Console. But no equinox or eclipse services are started, so I have no way to interact with my plugin. I don't want a felix shell - this is not sufficient - I need a full eclipse GUI started up... how can I do this? What capability is missing?

There is quite some tutorials around bndtools etc out there. But in 99% of cases they stop at felix. So I am stuck right now.

I also attach the generated MANIFEST in case this may be useful
