Problem updating a Provided Service's registered properties.
------------------------------------------------------------
Key: FELIX-84
URL: http://issues.apache.org/jira/browse/FELIX-84
Project: Felix
Type: Bug
Components: iPOJO
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.
