Generate OSGi infos in the manifest

[laeubi]

This pull request adds OSGi metadata support to the Java package and updates the Maven parent version. The main focus is on improving Java module compatibility with OSGi environments by updating the build configuration.

Java build and packaging improvements:

• Added the bnd-maven-plugin to pom.xml to generate OSGi metadata, enabling better integration with OSGi-based systems.
• Updated the maven-jar-plugin configuration in pom.xml to specify the manifest file location, which is necessary for proper OSGi metadata inclusion.
• Bumped the Maven parent version from 4.3.8 to 4.3.9 in pom.xml to ensure compatibility with the new plugins and features.

Documentation:

• Updated the CHANGELOG.md to document the addition of OSGi metadata for Java.This pull request adds support for OSGi metadata to the Java build, making the project more compatible with OSGi-based environments. The main changes involve updating the Maven build configuration and documenting the addition.

Build system enhancements:

• Added the bnd-maven-plugin and configured the maven-jar-plugin in pom.xml to generate OSGi metadata in the build artifacts.
• Updated the parent version in pom.xml to 4.3.9-SNAPSHOT to reflect the ongoing development state.

Documentation:

• Noted the addition of OSGi metadata in the CHANGELOG.md under the "Added" section.

This results in the following summary:

@mpkorstanje for me it all looks sane, can you review this?

[mpkorstanje]

LGTM. Please do add a link to this PR in the changelog.

Require-Capability: osgi.ee;filter:="(&(osgi.ee=JavaSE)(version=1.8))"

Just thought of something. But I don't know OSGI that well.

Are these module imports? If so, then the JavaSe version shouldn't be 1.8.

Are these module imports?

No these are packages

If so, then the JavaSe version shouldn't be 1.8.

The project is currently compiled with Java 1.8 bytecode that's why 1.8 is used here as the minimum version.

@mpkorstanje rebased to use the new parent, build should now succeed

Final outcome is:
