Hi,
I totally agree that it's a good thing that we can use PLC4X in an OSGI
environment and the changes are really minimal.
Also I have no problems with the refactoring of the packages ...

that's functionally not an is
As a former OSGi-buff, I think I need to provide a little bit

What Julian is talking about is how bundles are constructed according to
OSGi, i.e. more stuff in META-INF/MANIFEST.MF, and there is tooling support
to ensure this is done correctly, such as a Maven plugin,
Hi all,
with the help of the Karaf Community and especially @Christian Schneider I was

This means that all jars are also valid (and hopefully correct) OSGi Bundles.
Furthermore, I introduced a
I agree ... as far as I understand it it's just some text in the MANIFEST that
doesn't have impact on other class loading systems.
We should check how we get this additional data in there however. There are
multiple options and I don't quite know how good all of them are.

Am 08.10.19,
Hi Julian,
We should put the osgi metadata directly into the modules as they „just“
enhance the manifest.
Additional JARs would only increase the complexity.
