Optional injection not supported in JSR-330 integration - can we make an @Optional field annotation? #671

Optional injection not supported in JSR-330 integration - can we make an 
@Optional field annotation?  This would allow

@Inject @Optional
public MyOptionalService service;

Guice would still support previous behaviour but would treat @Optional on an 
@Inject-ed method as if it were com.google.inject.Inject(optional=true);

I talked to the reporter. We decided it's easiest to just inject null.
