james strachan commented on FELIX-4393:
---------------------------------------

Here's an example of its use:
https://github.com/fabric8io/fabric8/blob/master/gateway/gateway-fabric/src/main/java/org/fusesource/gateway/fabric/http/FabricHTTPGateway.java#L76

where we replicate the property name as the @Property(name = ) value and as the same as the field name. In this case the @Property is used to help auto-create the OSGi MetaType; we also use it (via the Configurer object) to inject the values into the fields from the Map<String,String> passed in @Activate and @Modified).

> it'd be nice if @Property behaved like various other annotations (e.g. @Inject / @Resource) so that if a name is not specified and @Property is specified on a field, then the name value defaults to the field name.
> It looks like name is optional with a default of "" - so its just the maven scr plugin which seems to barf if name is empty generating this kind of compile error:
> {code}
> @Property : Property name can not be empty.
> {code}
> It'd be nice if the name was optional; it makes the code more DRY and keeps things more refactoring safe etc
