> When constructor injection is used and a reference is only used as argument to the constructor it gets an automatically generated [reference name|http://docs.osgi.org/specification/osgi.cmpn/7.0.0/service.component.html#org.osgi.service.component.annotations.Reference.name--] by Bnd like {{$001}} (as constructor parameter names are not available in class files, https://docs.oracle.com/javase/8/docs/api/java/lang/reflect/Executable.html#getParameters--) which leads to the following error message when a reference cannot be injected:
> {code}
> org.apache.sling.testing.mock.osgi.ReferenceViolationException: Unable to inject mandatory reference '$001' for class <MyDSComponentClass> : no matching services were found.
> 	at org.apache.sling.testing.mock.osgi.OsgiServiceUtil.buildConstructorInjectionValue(OsgiServiceUtil.java:568)
> 	at org.apache.sling.testing.mock.osgi.OsgiServiceUtil.buildConstructorInjectionValues(OsgiServiceUtil.java:533)
> 	at org.apache.sling.testing.mock.osgi.OsgiServiceUtil.instantiateServiceWithActivateInject(OsgiServiceUtil.java:493)
> 	at org.apache.sling.testing.mock.osgi.OsgiServiceUtil.activateInjectServices(OsgiServiceUtil.java:456)

> 	at org.apache.sling.testing.mock.osgi.context.OsgiContextImpl.registerInjectActivateService(OsgiContextImpl.java:191)
> 	at org.apache.sling.testing.mock.osgi.context.OsgiContextImpl.registerInjectActivateService(OsgiContextImpl.java:179)
> 	...
> {code}
> In addition to the reference name the to be injected class should be emitted and also it should be mentioned that a constructor argument cannot be resolved.
