Re: [lyo-dev] Proposal for removing oslc4j-registry and oslc4j-wink
Hello,

We are further planning to remove the old Lyo client (Apache Wink based, abandoned since ca. 2015) that was carried over from 2.4 to help with the migration to 4.x:


This will lead to the removal of two clients in total in Lyo 5.0:


This will leave only one client implementation in the Lyo repo: https://github.com/eclipse/lyo/blob/master/client/oslc-client/pom.xml

The rationale is that we don't support Wink anymore, do not have bandwidth to test the old clients with JDK 11 and, most importantly, don't have the time to port bugfixes to the current client to the legacy one. Please note that we are NOT removing the old client's domain resource classes: 


They don't require much support and will remain as a legacy alternative to the new Lyo Domains that are generated using Lyo Designer: https://github.com/eclipse/lyo/tree/master/domains 

New client docs are located under https://download.eclipse.org/lyo/docs/all/latest/apidocs/org/eclipse/lyo/client/package-summary.html. I recall putting together a list of things one needs to keep in mind when migrating to the new client (from the wink oslc-java-client, there is no migration path from the client in oslc4j-wink) but cannot find those notes quickly. I will share them again when I dig them up.

Best regards,
Andrew

Hello everyone,

I was looking through our codebase for uses of Log4j and stumbled on oslc4j-registry, which was using Log4j 1.2 dependency (though it didn’t make use of it in the codebase, instead using java.util.logging.Logger for some reason) and its dependency, oslc4j-wink. I think those apps serve no useful purpose and can be removed in Lyo 5.0. Leave your comment here or under https://github.com/eclipse/lyo/pull/220 (has more details).

Regarding Lyo 5.0, we will have drop JDK 8 support and target JDK 11 as the baseline. More vulnerability notices are coming, most importantly about Jena and we don’t have bandwidth to try backporting them by hand to Jena 3.17.x. Lyo Designer already made the move to JDK 11 and OSLC Reference Implementation that uses Lyo runs well on JDK 8, JDK 11, and JDK 17. You feedback is also welcome here or in https://github.com/eclipse/lyo/issues/221. If you wish to step up to backport Jena CVE fixes for the old branch, please contact us. We are happy to use your fork if it gets published to Maven Central.

Cheers,
Andrew
