It looks like binding multiple optional references in OSGi is flaky at least with Felix 1.2.0. Uhh what does that mean?

AFAICT, an annotation like

@Reference(name="virtualResourceType",
 cardinality = ReferenceCardinality.OPTIONAL_MULTIPLE,
 referenceInterface = VirtualResourceType.class)

with

public void bindVirtualResourceType(VirtualResourceType virtualResourceType) {
    log.info("Bound "+virtualResourceType);
   store.put(virtualResourceType,virtualResourceType);
}
public void unbindVirtualResourceType(VirtualResourceType virtualResourceType) {
   log.info("UnBound "+virtualResourceType);
   store.remove(virtualResourceType);
}

Only binds some of the time on reload, but unbind works every time.

I have a feeling that below will work, no idea why ?

protected void bindVirtualResourceType(ServiceReference reference) {
   VirtualResourceType virtualResourceType =  (VirtualResourceType) this.componentContext.locateService(
       "VirtualResourceType", reference);
   if ( virtualResourceType != null ) {
      LOGGER.info("=====================BOUND VIRTUAL RESOURCE TYPE{}===============================",virtualResourceType.getResourceType());
      virtualResourceTypes.put(virtualResourceType.getResourceType(), virtualResourceType);
   } else {
      LOGGER.info("=====================Faied to find BOUND VIRTUAL RESOURCE TYPE{}===============================",reference);
   }
}

Update:

The annotation should have been

@Reference(name = “virtualResourceType”,
cardinality = ReferenceCardinality.OPTIONAL_MULTIPLE,
referenceInterface = VirtualResourceType.class,
policy = ReferencePolicy.DYNAMIC)

and then the bind and unbind can be

protected void bindVirtualResourceType(VirtualResourceType virtualResourceType) {
    virtualResourceTypes.put(virtualResourceType.getResourceType(), virtualResourceType);
}

protected void unbindVirtualResourceType(VirtualResourceType virtualResourceType) {
    virtualResourceTypes.remove(virtualResourceType.getResourceType());
}

(I am an idiot!)
