> The reason is that the jbi classloader is create with bundle urls
> pointing to the libraries embedded in the component.
> For example:
> bundle://72.0:1/lib/openjpa-1.1.0.jar
> Those URLs are resolved correctly to locate resources, so we end up
> with urls like:
>
> jar:bundle://72.0:1/lib/openjpa-1.1.0.jar!/org/apache/openjpa/kernel/localizer.properties
> Now, the problem is that they fail to be opened at the above point in
> the code. THis is because Felix is trying to find on the stack trace
> a classloader which is of type
> org.apache.felix.framework.searchpolicy.ContentClassLoader (in the
> URLHandlers#getFrameworkContext() method). But there's none because
> all classes are loaded from the JBI component classloader instead of
> a felix classloader in this case.
