I am getting an NPE in the code though when trying to add Felix.

The problem is that the framework instance was created from a project that doesn't contain any modules with Osmorc facets. In this case the used Equinox State object is not yet set and hence the NullPointerException appears.

Workaround till this is fixed:
Add the Osmorc facet to at least one module of the project, then create the framework instance.
