This transformed artifact can coexist with the javax namespace with "jakarta" classifier, and we don't have to maintain two branches until Jakarta EE10 and there are new features added. Other projects like hibernate and jackson use this shade plugin or Eclipse transformer to support jakarta ee9: https://github.com/hibernate/hibernate-orm/blob/main/hibernate-core-jakarta/hibernate-core-jakarta.gradle#L100 https://github.com/FasterXML/jackson-jaxrs-providers/blob/2.12/json/pom.xml#L115 > > To summarize briefly: > - release 3.5.0 in preparation to JDK-17 LTS, keeping JDK-8 as baseline > - move master to 3.6.x (4.x?) with JDK-11 as the minimal required JDK > version (Jetty 10, ...) > - branch off 5.x (4.x?) to continue the work on supporting Jakarta 9.0+, > with JDK-11 as the minimal > required JDK version (Jetty 11, ...) > > I think it is very clear that maintaining JavaEE + JDK8 / JavaEE + JDK11 / > Jakarta + JDK11 would consume > much more time from the team, but I am not sure we have other options if > we aim to evolve and keep CXF > up to date.
