Hi, I think I have a decent solution for testing of distributed execution and CDI in the place now. Galder helped out a lot! However, I still can not bridge the last remaining mystery: I have two tests WordCountMapReduceCDITest and DistributedExecutorCDITest. When both tests are enabled WordCountMapReduceCDITest fails as it is run second. If only either one of the tests is enabled - everything works as expected. Pick up pull request at https://github.com/infinispan/infinispan/pull/982 , first maven install core and then proceed to cdi/extension to give test suite a run. You can see the root of the failure in surefire reports. Weld somehow cannot resolve bean passed to InjectionTarget inject method. Much appreciated, Vladimir Caused by: org.jboss.weld.exceptions.IllegalArgumentException: WELD-001324 Argument bean must not be null at org.jboss.weld.manager.BeanManagerImpl.getReference(BeanManagerImpl.java:657) at org.jboss.weld.injection.FieldInjectionPoint.inject(FieldInjectionPoint.java:118) at org.jboss.weld.util.Beans.injectBoundFields(Beans.java:703) at org.jboss.weld.util.Beans.injectFieldsAndInitializers(Beans.java:712) at org.jboss.weld.manager.SimpleInjectionTarget$1.proceed(SimpleInjectionTarget.java:106) at org.jboss.weld.injection.InjectionContextImpl.run(InjectionContextImpl.java:48) at org.jboss.weld.manager.SimpleInjectionTarget.inject(SimpleInjectionTarget.java:102) at org.infinispan.cdi.CDIDistributedTaskLifecycle.onPreExecute(CDIDistributedTaskLifecycle.java:46) at org.infinispan.distexec.spi.DistributedTaskLifecycleService.onPreExecute(DistributedTaskLifecycleService.java:80) at org.infinispan.commands.read.MapReduceCommand.perform(MapReduceCommand.java:144) _______________________________________________ infinispan-dev mailing list infinispan-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/infinispan-dev
