PH27629: CDI RESOURCE INJECTION OF MANAGEDEXECUTORSERVICE

APAR status

• Closed as program error.

Error description

• When an object is registered in JNDI as multiple types, trying
  to perform @Resource injection from inside a CDI-managed bean
  would cause validation to fail in some cases.
  https://github.com
  /OpenLiberty/open-liberty/pull/13055
  
  Example: using a separate
  ManagedExecutorService (not the default one) with CDI.
  The code
  looks like this:
  @Dependent
  class ResourcesProducer
  {
  @Resource(lookup =
  "concurrent/sampleExecutor")
  @Produces
  private
  ManagedExecutorService sampleExecutor;
  }
  This gives to the
  following deployment error:
  Caused by:
  javax.enterprise.inject.spi.DefinitionException: CWOWB1007E:
  The producer field,
  ch.css.sample.srv.ejb.ResourcesProducer.sampleExecutor, has
  type javax.enterprise.concurrent.ManagedExecutorService, which
  does not match the type of the injected object.

  The same code
  works if we make an indirection via the java:app namespace in
  an ejb:
  @Stateless
  public class DummyBean {
  @Resource(name =
  "java:app/env/concurrent/sampleExecutor", lookup =
  "concurrent/sampleExecutor")
  private ManagedExecutorService
  sampleExecutor;
  }

  ****************************************************************
  An injected object was not matching it's JNDI definition.This
  can occur if an object is registered in JNDI under multiple
  interfaces
  

Problem conclusion

• If the class registered in JNDI does not match the injected
  class we now fallback to actually
  performing a JNDI lookup to check if its assignable
