An annotated TransactionAttributeType is not applied to a inherited EJB-Method

Issue

There seems to be a bug impacting the EJB configuration via annotations.
Two different SessionEJBs BeanA and BeanB with the following annotations defined at class level

   @TransactionManagement(TransactionManagementType.CONTAINER) 
   @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW) 

BeanB inherits methods from its superclass but does not override any of them

Code Snippet

------------------
BeanA.java
------------------
@Stateless(name="BeanA")
@TransactionManagement(TransactionManagementType.CONTAINER)
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
public class BeanA implements BeanARemoteInterface {

        @Override
        public void testMethod() throws Exception {
           .. .. ..
        }
-------------------
BeanB.java
-------------------
@Stateless(name="BeanB")
@TransactionManagement(TransactionManagementType.CONTAINER)
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
public class BeanB extends SimpleBaseClass implements BeanBLocalInterface  {
        //All functionality is defined in SimpleBaseClass!      
}
-------------------

public class SimpleBaseClass  {
        public void testMethod() throws Exception {             
                .. .. ..
        }

• A remote call invokes BeanA#testMethod() and and subsequently BeanA#testMethod() invokes BeanB#testMethod() (which is inherited from the superclass SimpleBaseClass)

Although BeanB requires a new transaction, the BeanB#testMethod() is executed within the same transaction.
This buggy behaviour occurs only if the TransactionAttributeType is set via annotation. If the trans-attribute is set via ejb-jar.xml, then both EJBs are operating as expected in two different transactions.
