Florian,
I believe that part of the answer to your problem is explained in
section 3.5.6 "Exporting and Importing a Package" of the core OSGi spec,
which states that "Bundles should import exported packages, allowing the
resolver to substitute packages that contain interfaces and other shared
types."
A condensed explanation by Rick Hall is also available here:

Hello!
I'm using the Maven-Bundle-Plugin and having problems with specifying
export-package and import-package.
Since my package structure in java does not fit the default export-package
(<groupId>.<artifactId>.*), I specify this on my own:
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Export-Package>deus.model.*</Export-Package>
</instructions>
</configuration>
</plugin>
The effect is, that all packages are exported (good!) and that also, all
packages contained in the bundle appear in the field Import-Package, although,
they are contained in the bundle (not so good).
Why?
If I exclude the packages from this bundle from importing:
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<extensions>true</extensions>
<configuration>
<instructions>
<Export-Package>deus.model.*</Export-Package>
<Import-Package>!deus.model.*,*</Import-Package>
</instructions>
</configuration>
</plugin>
All packages being in Import-Package before now appear in the header
Ignore-Package (it's getting worse...). What is this header for?
I can't imagine how to simply export all classes of my package while not
importing the packages contained in the bundle.
To further complicate this (actually not so complicated) issue, I would like to prevent
everything inside an "impl" package from getting exported.
How to do this?
<Export-Package>!*.impl,deus.model.*</ExportPackage>
would fit my needs perfectly, but it looks like the wildcard * is only
recognized at the end of a package path pattern.
I would really be glad, if somebody could help me, these issues really drive me
crazy.
Thanks a lot!
Florian
