> 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.

> 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.
