--------------------------------
> Problem updating a Provided Service's registered properties.
> ------------------------------------------------------------
>
> Key: FELIX-84
> URL: https://issues.apache.org/jira/browse/FELIX-84
> Project: Felix
> Issue Type: Bug
> Components: iPOJO
> Affects Versions: 0.8.0
> Reporter: John Conlon
>
> Experiencing intermittent NPEs when Configuration Admin updates the
> properties of a registered provided service and m_serviceRegistration is null.
> Have seen this behavior in two variations, both intermittent.
> 1. When a component specifies a ConfigurableProperty in the metadata and the
> ConfigurationHandler is acting as the ManagedService. Here is the log of
> this condition:
> INFO [Update Consumer]
> org.apache.configuration.impl.UpdateConsumer.updateManagedService(UpdateConsumer.java:245)
> - Invoking updated on [EMAIL PROTECTED], with
> configuration=org.apache.configuration.impl.ConfigurationDictionary [
> event.topics=com/verticon/rfid, service.pid=com.verticon.react2,
> objectclass=[react2Server, apacheServiceConfiguration, top],
> event.filter=(event.topics=*), cn=react2Server ]

> 2. The second condition is when a component that has specified a
> ManagedService as a ProvidedService and this component attempts to directly
> update a property that was specified as a child property element to the
> ProvidedService in the metadata.
