> h2. Issue description:
> During migration from Wildfly 8.1 to 8.2 (Weld 2.1.2.Final -> 2.2.6.Final) in Infinispan we discovered a problem with injecting beans created programmatically in Infinispan-cdi integration module. The problem appeared in {{GreetingServiceIT}} and {{GreetingCacheManagerIT}} test. Both those tests use the following modules integrated into Wildfly:
> * org.infinispan.cdi (slot: ispn-7.1, which has dependency to "org.infinispan" slot="ispn-7.1" export="true")
> * org.infinispan.jcache (slot: ispn-7.1, which has dependency to "org.infinispan" slot="ispn-7.1" and "org.infinispan.cdi" slot="ispn-7.1" services="import")
> [Infinispan's CDI Extension|https://github.com/infinispan/infinispan/blob/master/cdi/src/main/java/org/infinispan/cdi/InfinispanExtension.java] invokes [{{embeddedExtension.registerCacheBeans(event, beanManager)}}|https://github.com/infinispan/infinispan/blob/master/cdi/src/main/java/org/infinispan/cdi/InfinispanExtensionEmbedded.java], which registers custom {{Cache}} and {{AdvancedCache}} producer beans. Those beans are being successfully added to {{BeanManager}} but are never chosen for injection. All tests fail because of unsatisfied dependencies for {{Cache<CacheKey, String>}} with qualifiers {{@GreetingCache}}.
> h2. Steps to reproduce:
> * Download and unzip [https://github.com/slaskawi/infinispan/archive/upgrade_to_wf_8_2_failed_test.zip]
> * Run {{./build.sh clean install -pl cdi,as-modules/embedded,integrationtests/as-integration-embedded -am -DskipTests}}
> * Modify Arquillian xml if breakpoint is needed {{./integrationtests/as-integration-embedded/src/test/resources/arquillian.xml}}
> * Run test (using IDE or Maven: {{./build.sh test -pl integrationtests/as-integration-embedded -Dtest=GreetingServiceIT}})
> h2. Finding during debugging:
> At first I would suggest creating conditional breakpoints:
> * {{org.jboss.weld.bootstrap.Validator}} line 370 (WF 8.2) or 366 (WF 8.1), condition {{"[BackedAnnotatedField] @Inject @GreetingCache private org.infinispan.test.integration.as.cdi.GreetingServiceIT.greetingCache".equals(ij.toString())}} - this will stop debugger when validating injection points for {{{GreetingCache}}.
> * {{org.jboss.weld.resolution.TypeSafeResolver.ResolvableToBeanCollection}} line 51, condition {{from.toString().startsWith("Types: [org.infinispan.Cache<javax.cache.annotation.CacheKey, java.lang.String>]") || from.toString().contains("org.infinispan.Cache")}} - this stops debugger on loading {{Cache}} producer methods (created in Infinispan CDI Extension) to {{resolved}} Loading Cache in Wildfly 8.1.
> During debugging session we discovered that the beans from Infinispan's CDI Extension are created but never used for injection. This is because {{beanManager.getBeans(ij)}} in {{Validator.java}} always return empty list. In Wildfly 8.1 beans are properly resolved using {{ResolvableToBeanCollection#load}} method, but for some reason it never happens in Wildfly 8.2, because those beans are already preset in {{resolved}} Loading Cache with empty collection value. Unfortunately we couldn't find answer why.
> h2. Workaround:
> In order to fix CDI Producer Beans accessibility we need to add a new dependency to our test: {{META-INF/MANIFEST.MF: Dependencies: org.infinispan:ispn-7.1}}.
