As part of OAK-1741 I was changing the Version of exported packages to 1.0.0. Looking at the interfaces which are part of exported packages I do not see usage of ConsumerType/ProviderType annotations [1]
In brief and simple terms the interfaces which are expected to be implemented by users of Oak api (like org.apache.jackrabbit.oak.plugins.observation.EventHandler) should be marked with ConsumerType anotation. This enables bnd tool to generate package import instructions with stricter range [1.0,1.1) For all other interface which are supposed to be provided by Oak we should mark them with ProviderType. This enables bnd to generate the package import instructions with relaxed range [1.0,2) for our api consumers. This would help us evolve the api in future easily. Currently we are having following interfaces as part of exported packages [2]. Looking at the list I believe most are of ProviderType i.e. provided by Oak and not required by Oak API users. Some like org.apache.jackrabbit.oak.plugins.observation.EventHandler are of ConsumerType as we require the API users to implement them. Should we add the required annotations for 1.0 release? If yes then can team members look into the list and set the right type Chetan Mehrotra [1] https://github.com/osgi/design/raw/master/rfcs/rfc0197/rfc-0197-OSGiPackageTypeAnnotations.pdf [2] https://issues.apache.org/jira/browse/OAK-1741?focusedCommentId=13979465#comment-13979465
