Hi, I'm not sure to follow your point.
In Karaf 4.2.x, openjpa3 just installs the xbean-asm bundle and the full "native" openjpa feature. If you take a look on the openjpa feature: https://repo1.maven.org/maven2/org/apache/openjpa/openjpa-features/3.0.0/openjpa-features-3.0.0-features.xml It installs the required bundles and the "main" openjpa 3 bundle. So it's basically the same. I would more use directly OpenJPA 3.
