------------------------------------------------------------------
Right now the component property type object returns {{null}} for all methods,
which are not given in the {{HashMap}} in
https://github.com/apache/felix/blob/trunk/scr/src/main/java/org/apache/felix/scr/impl/inject/Annotations.java#L246.
Instead of the simple {{Handler}} class one must implement something similar to
{{sun.reflect.annotation.AnnotationInvocationHandler}}. There is such a code in
bytebuddy (Apache License 2.0)
(https://github.com/raphw/byte-buddy/blob/master/byte-buddy-dep/src/main/java/net/bytebuddy/description/annotation/AnnotationDescription.java)
one could maybe just embed.

> URL: https://issues.apache.org/jira/browse/FELIX-5543
> Project: Felix
> Issue Type: Bug
> Components: Declarative Services (SCR)
> Affects Versions: scr-2.1.0
> Reporter: Konrad Windszus
>
> Currently component property types only implement one getter method for each
> element. The methods {{toString()}}, {{equals()}}, {{hashCode()}} and
> {{annotationType}} are not implemented properly (i.e. all return just
> {{null}}). This violates JLS 9.6
> (https://docs.oracle.com/javase/specs/jls/se7/html/jls-9.html#jls-9.6).
> bq. The direct superinterface of an annotation type is always
> java.lang.annotation.Annotation.
> The component property type needs to implement
> {{java.lang.annotation.Annotation}} and all its methods properly. The current
> implementation is clearly violating the contract of the
> {{java.lang.annotation.Annotation}}.
> For that the {{Annotations#toObject(...)}} needs to be adjusted in
> https://github.com/apache/felix/blob/trunk/scr/src/main/java/org/apache/felix/scr/impl/inject/Annotations.java#L41.
