------------------------------------
Summary: ComponentContext.getServiceReference returns null though
service registered
Key: FELIX-5213
URL: https://issues.apache.org/jira/browse/FELIX-5213
Project: Felix
Issue Type: Bug
Components: Declarative Services (SCR)
Affects Versions: scr-2.0.2
Reporter: Neil Bartlett
In a component that provides a service and is not immediate, the service is
registered before activation. Therefore the service reference of the registered
service should be available to the component, from
ComponentContext.getServiceReference(), during activation. However the
following code sample throws NPE:
{code}
import org.osgi.framework.Constants;
import org.osgi.framework.ServiceReference;
import org.osgi.service.component.ComponentContext;
import org.osgi.service.component.annotations.Activate;
import org.osgi.service.component.annotations.Component;
@Component(service = Object.class, property = "name=scrbug")
public class Example {
@Activate
void activate(ComponentContext context) {
ServiceReference<?> reference = context.getServiceReference();
System.out.printf("My service ID is %d%n",
reference.getProperty(Constants.SERVICE_ID));
}
}
{code}
Note that the service certainly exists, because I have injected it into a
second component, in order to force activation of the above.
