> In the OSGi CT, the testActivateDeactivate(org.osgi.test.cases.component.junit.DeclarativeServicesControl) method tests that that component activate and deactivate methods are properly called. It uses ComponentContext.disableComponent and enableComponent to cause component instances to be disposed and created.
> If ComponentContext.enableComponent is called on an already enabled component, SCR will improperly create an additional instance of the component.
> See the following log messages:
> org.osgi.test.cases.component.tb6.CcBcMapIntNS110@1048641931 activate
> org.osgi.test.cases.component.tb6.ContExp@339127939 activate
> configuration update org.osgi.test.cases.component.tb6.CcBcMapIntNS110
> configuration updated org.osgi.test.cases.component.tb6.CcBcMapIntNS110
> org.osgi.test.cases.component.tb6.CcBcMapIntNS110@1048641931 deactCcBcMapInt
> org.osgi.test.cases.component.tb6.CcBcMapIntNS110@855459426 activate
> enable org.osgi.test.cases.component.tb6.CcBcMapIntNS110
> enabled org.osgi.test.cases.component.tb6.CcBcMapIntNS110
> org.osgi.test.cases.component.tb6.CcBcMapIntNS110@232400695 activate
> We can see that CcBcMapIntNS110 is activated initially. Then in response to a configuration change, the component instance is deactivated and a new instance it activated. Then ComponentContext.enableComponent is called on the already enabled component and another instance is created in error.
> This error is creating problems passing the OSGi CT.
