We have already discussed the problem of interceptorLookup for PartialBean on Wildfly. IMHO due to subdeployment CL-visibilty issues (not flat!) the interceptors in jar A are not visible in jar DS-partial-bean-impl.
A possible solution for this can be: BeanMangerProvider#getBeanManager(): extend decision on lookup strategy like private static boolean useDelegateLookup() { return CoreBaseConfig.BeanManagerIntegration.DELEGATE_LOOKUP && System.getProperty("jboss.server.name") == null; } Then all tests in partial-bean-impl -P wildfly-build-managed run successfully! Another issue that could be resolved this way: TransactionStrategy lookup in data-impl: Instead of @Priority workaround - activate ContainerMangedTxStrategy in beans.xml - and change Injection of TransactionStrategy in TransactionalQueryRunner like: protected Object executeTransactional(final QueryBuilder builder, final CdiQueryInvocationContext context) { TransactionStrategy strategy = BeanProvider.getContextualReference(TransactionStrategy.class); will also work fine! Just to show the massive impact of the identified (supposed?) bug in Wildfly subdeployment class visibility. First step: your feedback on the proposed (temporary?) fix on abovementioned change in BeanManagerLookup :-/
