> As described [in dev@karaf.apache.org list|http://karaf.922171.n3.nabble.com/Idea-how-to-override-bundle-headers-without-wrap-tp4055414.html]
I'd like to think about mechanism similar to one implemented with KARAF-5376, but concerning
bundles themselves.
> When features service checks (to resolve) and installs a bundle, it could _transform_
it according to some rules.
> Currently I have idea about fixing Manifest headers, in order for example to widen {{javax.servlet}}
API import range. That's common case with every major JavaEE/ServletAPI release that it breaks
current applications even if it's fully compatible.
> Without pasting everything I posted to mailing list, here's example configuration within
{{etc/org.apache.karaf.features.xml}}:
> {code:xml}
> <bundleProcessing>
>     <bundle location="mvn:org.eclipse.jetty*/*">
>         <add header="Processed-By" value="Karaf Bundle Processor" />
>         <clause header="Import-Package" name="javax.servlet"
> value='javax.servlet;version="[3.1.0,5)"' />
>         <clause header="Import-Package" name="javax.servlet.annotation"
> value='javax.servlet.annotation;version="[3.1.0,5)"' />
>         <clause header="Import-Package" name="javax.servlet.descriptor"
> value='javax.servlet.descriptor;version="[3.1.0,5)"' />
>         <clause header="Import-Package" name="javax.servlet.http"
> value='javax.servlet.http;version="[3.1.0,5)"' />
>     </bundle>
> </bundleProcessing> 
> {code}
> Processed bundles go (by default) to {{$&#123;karaf.data&#125;/repository-bpr}}
and then are resolved using _default repositories_ feature of pax-url-aether.
