how to add bus extension to the existing bus on the osgi env?

[XiLai Dai]

Hi,

We have a CustomerFactoryBeanListener looks like:
public class RegistryFactoryBeanListener implements FactoryBeanListener {
public void handleEvent(Event ev, AbstractServiceFactoryBean factory, Object... 
args) {
        switch (ev) {
        case CLIENT_CREATED: {
          // do something
        }case SERVER_CREATED: {
          // do something
        }
}
}

And register this class to the bus as a extension (add a line to 
META-INF/cxf/bus-extensions.txt)

There have some existing cxf buses/services installed on the osgi (karak) 
container before we install this extension bundle into container, the problem 
is the extension isn't added to these "old" buses. (it only works for the new 
installed buses/services)

Is it an know issue or maybe a cxf extension problem? Any workaround? Now we 
have to refresh the "old" bundles (with cxf bus) manually to get the extension 
added.

Thanks!
