OSGi-Support

[stbischof]

Use case

1. I want to run the clickhouse jdbc drivers inside an OSGi Framework.
2. I would like to use the OSGi -pecifies DatasourceFactory.

Describe the solution you'd like

1. Use bnd-jar-plugin to generate a proper Manifest.MF file that is needed for OSGI-Bundles(jars)
2. Implement the DatasourceFactory.

Describe alternatives you've considered

write manifest by hand

Additional context

I could make a PR if someone i get green light for this.

I am currently working on some improvements with bnd to generate the manifest. How important is the java 9 support for you? what is the minimum target version? And do you really need this multi version support?

How important is the java 9 support for you?

JMPS was introduced since JDK 9 - that's the only reason of put module-info.java under java9 directory, in case someone uses JDK 9(in most cases should be one of 8, 11 and 17). I guess we can change to 11 if that helps.

what is the minimum target version?

JDK 8. I hope we can upgrade to 11 in 0.4.

And do you really need this multi version support?

It's still important because I'm testing Vector API, which was introduced since JDK 16, revised in 17. In my local, I added java17 directory and will check in if the performance is really good. Anyway, I think you can create a shaded jar like this for JDK 8+ without consideration of 9, 11 or 17.
