(iPOJO) NPE when injecting BundleContext and @Requires in constructor

[Anthony Bargnesi]

Hi folks,

I have an iPOJO service component that takes two constructor parameters:
  - BundleContext
  - another service with @Requires

My scenario is similar to the following contrived example:

@Component
@Provides
@Instantiate
public class DefaultUserService implements UserService {
     ...
}

@Component
@Provides
@Instantiate
public class DefaultPersonService extends ObjectService implements
PersonService {

     private final BundleContext ctx;

     public DefaultPersonService(BundleContext ctx,
         @Requires(nullable = false, proxy = false)
UserService userService) {

         super(userService);
         this.ctx = ctx;
     }
}

In my example I require ObjectService to be instantiated with the
UserService so it must
be a constructor parameter.

I found that if I also want BundleContext to be injected then I receive the
following
NullPointerException:

If I remove the BundleContext constructor parameter then the UserService is
injected and the DefaultPersonService
is valid.

I have tested this against the latest trunk code at:
https://svn.apache.org/repos/asf/felix/trunk/ipojo/

I thought it could be related to the following fix:
https://issues.apache.org/jira/browse/FELIX-3576

Could this be a bug?

Thanks!
