Thomas Watson commented on FELIX-3522:
--------------------------------------
One nit in your testcase with the following code:
Requirement req = wire.getRequirement();
String pkgname = (String)
req.getAttributes().get(PackageNamespace.PACKAGE_NAMESPACE);
My understanding is that the osgi.wiring.package namespace requirements (as
constructed from the Import-Package header) must have an empty attribute map
since all the attributes are used for the filter directive. In my
implementation of Requirement for the osgi.wiring.package namespace I certainly
have an empty map and this would return a null req.
