]
Felix Meschberger closed FELIX-1436.
------------------------------------
Resolution: Fixed
In Rev. 799809, enhanced theComponentMetadata class to be able to verify
exactly one implementation element and at most one service element has been
declared. Also added unit tests to verify the validation procedure.
> Descriptors with duplicate implementation and/or service elements are invalid

> Key: FELIX-1436
> URL: https://issues.apache.org/jira/browse/FELIX-1436
> Project: Felix
> Issue Type: Bug
> Components: Declarative Services (SCR)
> Affects Versions: scr-1.0.8
> Reporter: Felix Meschberger
> Assignee: Felix Meschberger
> Fix For: scr-1.2.0
>
>
> The DS specification states that the implementation element must be listed
> exactly once in a descriptor. Likewise the service element may be listed at
> most once. Currently these elements may be repeated and the parser will just
> happily accept the last element as the declaration.
> This is incorrect. Descriptors with duplicate implementation and/or service
> elements must not be accepted and rejected by metadata validation. By not
> rejecting it at parse time we make logging easier and also enable easier
> implementation of accepting valid descriptors along invalid descriptors in
> the same XML document.
