I don't think you should do it this way...

1. first, if you deal with a distribution where gms is not present, this will fail
2. you start importing implementation types which makes your imports/exports more complicated.

why not doing :

@Service(name="gms")
public class GMSConfigUpgrade implements ConfigurationUpgrade, PostConstruct {...}

and in your upgrade service, just do

> + @Inject(name="gms", optional=true)
> + ConfigurationUpgrade notUsed=null;

that way you still only depends on ConfigurationUpgrade type and it does not fail if gms is not present.

Thus, it's now in the same package as similar classes (e.g. GrizzlyConfigSchemaMigrator). So the whole fix is 4 lines of code plus comments. I think Tim actually gave me this idea, courtesy of Jerome:
