title: Spring Data JPA repositories use in EJB timer causes TransactionRequiredException
body: <p>I would like to use spring data repositories in my Java EE project. I use:</p>
  
  <ul>
  <li>WildFly 10.0.0</li>
  <li>Hibernate 5.0.7 </li>
  <li>Spring Data JPA 1.10.6 </li>
  <li>CDI instead of Spring DI</li>
  </ul>
  
  <p>I have created the following classes and interfaces:</p>
  
  <pre><code>@Entity
  public class TestEntity {
      @Id
      @GeneratedValue(strategy = GenerationType.IDENTITY)
      private Long id;
  
      @NotNull
      @Size(min = 1, max = 32)
      @Column(name = "name")
      private String name;
  
      public Long getId() {
          return id;
      }
  
      public void setId(Long id) {
          this.id = id;
      }
  
      public String getName() {
          return name;
      }
  
      public void setName(String name) {
          this.name = name;
      }
  }
  </code></pre>
  
  <p>My repository</p>
  
  <pre><code>@Repository
  public interface TestRepository extends CrudRepository&lt;TestEntity, Long&gt; {    
      List&lt;TestEntity&gt; findByName(String name);
  }
  </code></pre>
  
  <p>My CDI Configuration</p>
  
  <pre><code>public class CdiConfig {
      @Produces
      @Dependent
      @PersistenceContext
      public EntityManager entityManager;
  }
  </code></pre>
  
  <p>My EJB Bean</p>
  
  <pre><code>@Stateless
  public class TestEJB {
      @Inject
      private TestRepository testRepository;    
  
      @TransactionAttribute(TransactionAttributeType.REQUIRED)
      public void testRepository() {
          TestEntity testEntity = new TestEntity();
          testEntity.setName("Some name");
          this.testRepository.save(testEntity);
      }
  }
  </code></pre>
  
  <p>My persistence.xml:</p>
  
  <pre><code>&lt;persistence xmlns="http://java.sun.com/xml/ns/persistence"

      &lt;persistence-unit name="[my data source]" transaction-type="JTA"&gt;
          &lt;jta-data-source&gt;java:/[my data source]&lt;/jta-data-source&gt;
  
          &lt;mapping-file&gt;META-INF/database-views.xml&lt;/mapping-file&gt;
  
          &lt;properties&gt;
              &lt;property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQL9Dialect"/&gt;
              &lt;property name="hibernate.hbm2ddl.auto" value="create"/&gt;

              &lt;property name="hibernate.jndi.url" value="java:/TransactionManager"/&gt;
          &lt;/properties&gt;
      &lt;/persistence-unit&gt;
  &lt;/persistence&gt;
  </code></pre>
  
  <p>If I invoke testRepository method (I use scheduler for this purpose) first time then I get the following exception:</p>

  <p>If I invoke testRepository method second time then everything is ok. Moreover, the problem does not occur if I remove findByName method from repository (this method is never invoked). Why?</p>
