New OSGi Code Error #10

Closed QNENet closed 3 years ago

QNENet commented 3 years ago

Rather than continue with my battle with V14 compatibility mode, over the weekend I decided to spend the time to investigate the new OSGi code.

The approach appears to be a significant improvement on the previous instantiator etc..

Although the new base-starter compiles perfectly, when trying to run it I get the error below.

I have already started the process to create a Karaf "feature module" but this error is preventing further progress in this task.

Realizing that it is very early in the implementation and testing of the new OSGi approach I would like to be involved at this stage, to help Vaadin, where ever I can, to achieve a very successful outcome for the new OSGi approach.

Especially using it with Karaf.

For many years I had been totally convinced that bnd and bndtools was the the only "pure" way to use OSGi.

Since changing to Karaf my project has advanced at a much greater pace than with bnd and bndtools.
