Subject [jira] [Commented] (FELIX-3576) iPOJO fails when using constructor injection and expecting BundleContext in ctor

Anthony Bargnesi commented on FELIX-3576:
-----------------------------------------

A similar issue is still occurring.  If I define a component with a constructor that takes
another required component and a BundleContext then I receive the following stacktrace:
{code:title=Bar.java|borderStyle=solid}
  [2012-10-16 16:11:11.886] ERROR iLogServiceListener@65284069 org.osgi.service.log.LogService

An example component definition that reveals this issue is:

{code:title=Bar.java|borderStyle=solid}
@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;
        }
    }
{code}
