Richard S. Hall commented on FELIX-2532:
----------------------------------------

There are a couple issues here:

1. I believe that OBR doesn't handle implicit attributes (i.e., bundle-symbolic-name and bundle-version) on exported packages at all. The proposed patch is only a partial solution for this limitation, e.g., it doesn't address bundle-version.

2. The proposed patch is not really correct either, since it simply replaces the implementation-specific system bundle name with the generic one (i.e., system.bundle), but what happens if someone is importing it with the implementation name? For system bundle, there actually needs to be a special case where this attribute is multi-valued.

> I have a bundle importing javax.xml.bind specifically from the system.bundle. The import looks like this:
> Import-Package: javax.xml.bind;bundle-symbolic-name=system.bundle
> Bindex translates the import into the following requirement:
>     <require extend='false' filter='(&amp;(package=javax.xml.bind)(version&gt;=0.0.0)(bundle-symbolic-name=system.bundle)(mandatory:&lt;*bundle-symbolic-name))' multiple='false' name='package' optional='false'>   
>       Import package javax.xml.bind
>     </require>
> This requirement is not resolved by the RepositoryAdmin service.
> When I loop over resolver.getUnsatisfiedRequirements(), I log:
> Unsatisfied OBR requirement (&(package=javax.xml.bind)(bundle-symbolic-name=system.bundle)(mandatory:<*bundle-symbolic-name))
> It seems that the bundle-symbolic-name constraint is not handled by the resolver.
