Hi Ralf, Are you using JDK8 or JDK11 ?
Jakarta Activation 1.2.2 bundle seems to require Java >= 9. You have two options: - wrap the bundle to remove ee requirement header (I did that in ActiveMQ bundles for instance) - upgrade to Java 11 ;) Regards JB > Le 21 déc. 2021 à 15:56, Ralf Steppacher <r...@steppacher.name> a écrit : > > Hello all, > > I am trying to migrate an application from Karaf 4.0 to Karaf 4.2.12, Camel > 2.25, and Spring 5.3.
