Hi All,
On App startup, if Entity X in bundle A extends Entity Y in bundle B and bundle A depends on bundle B I get NullPointerException (s.below). It's happened only at startup. After all bundles are loaded, and I create my own EntityManager - everything is fine. If All Entities are in the same bundle is everything fine too.
Any ideas how to make it correctly ?
