Hello, Do you have some guide for upgrading from karaf 4.1.x line to 4.2.x line?
I have a legacy app that wasn't possible to upgrade because of some critical bugs introduced with library updates (PostgreSQL support issues), now I've tried to install our app from 4.1.3 to 4.2.4 and I'm getting errors that are totally puzzling me: org.osgi.service.blueprint.container.ComponentDefinitionException: Unsupported node namespace: http://aries.apache.org/xmlns/transactions/v2.0.0 java.lang.LinkageError: loader constraint violation in interface itable initialization: when resolving method "org.apache.aries.jpa.container.impl.AriesEntityManagerFactoryBuilder.createEntityManagerFactory(Ljava/util/Map;)Ljavax/persistence/EntityManagerFactory;" the class loader (instance of org/apache/felix/framework/BundleWiringImpl$BundleClassLoader) of the current class, org/apache/aries/jpa/container/impl/AriesEntityManagerFactoryBuilder, and the class loader (instance of org/apache/felix/framework/BundleWiringImpl$BundleClassLoader) for interface org/osgi/service/jpa/EntityManagerFactoryBuilder have different Class objects for the type javax/persistence/EntityManagerFactory used in the signature Our app installs Aries JPA 2.7.0 (mvn:org.apache.aries.jpa/jpa-features/2.7.0/xml/features). Is there anything that need to be upgraded etc.? Thank you for any hints. Best regards, Lukasz Lech
