Dmytro Pishchukhin created FELIX-3787:
-----------------------------------------

             Summary: NPE on reference update
                 Key: FELIX-3787
                 URL: https://issues.apache.org/jira/browse/FELIX-3787
             Project: Felix
          Issue Type: Bug
          Components: Declarative Services (SCR)
    Affects Versions: scr-1.6.2
            Reporter: Dmytro Pishchukhin


I defined reference with annotation:
    @Reference(referenceInterface = Controller.class, cardinality = ReferenceCardinality.MANDATORY_UNARY,
policyOption = ReferencePolicyOption.GREEDY)
    protected Controller controller;

when I install a new service I got an error:
java.lang.NullPointerException
