> There are a couple of places in the SCR code where it gets the bundle object
> from ServiceReference.getBundle(). Unfortunately this method can return null
> when a service becomes unregistered. This can lead to FrameworkEvent errors
> with NPEs that look like the following:
> {code}
> FrameworkEvent ERROR java.lang.NullPointerException
> at
> org.apache.felix.scr.impl.runtime.ServiceComponentRuntimeImpl.serviceChanged(ServiceComponentRuntimeImpl.java:491)

> {code}
> We should protect against such cases.
