             Summary: NPE when invoking a lifecycle runnable method from init 
method
                 Key: FELIX-5956
                 URL: https://issues.apache.org/jira/browse/FELIX-5956
             Project: Felix
          Issue Type: Bug
          Components: Dependency Manager Runtime
    Affects Versions: org.apache.felix.dependencymanager-r1
            Reporter: Pierre De Rop
            Assignee: Pierre De Rop
             Fix For: org.apache.felix.dependencymanager-r12


When you use a DM lifecycle controller in order to trigger component activation 
from the @Init method, a NPE is throw if you invoke the lifecylce runnable from 
the init method.

For example, the following code:

{code:java}
@Component
public class MyServiceImpl implements MyService {

    @LifecycleController
    volatile Runnable _start;

    @Init
    void init() {
        _start.run(); // immediately trigger service activation
    }
}
{code}

produces the following NPE:
