Re: [aspectj-users] debugging "with runtime test"?

[Barry Kaplan <groups1@xxxxxxxxxxx>]

Here's some more detail.

The code to be advised:

public class ToBeAdvised {

   @PersistenceContext
   private EntityManager em;

   public void useEM() {
       em.flush();
   }
}


Here is a set of pointcuts/advise. All but one is indicated by AJDT as 
being conditionally advised. But at runtime only the first advise is 
actually invoked.

   //---- matches in AJDT, invoked at runtime
  
   @Pointcut("get(@javax.persistence.PersistenceContext 
javax.persistence.EntityManager *.*)")
   void entityManagerFieldGet_1(){}
      
   @Around("entityManagerFieldGet_1()")
   public EntityManager getEntityManager_1(JoinPoint jp){
       System.err.println("****getEntityManager_1");
       return null;
   }

   //---- matches in AJDT, not invoked at runtime
  
   @Pointcut("get(@javax.persistence.PersistenceContext 
javax.persistence.EntityManager *.*) && args(..)")
   void entityManagerFieldGet_2(){}
      
   @Around("entityManagerFieldGet_2()")
   public EntityManager getEntityManager_2(JoinPoint jp){
       System.err.println("****getEntityManager_2 ..");
       return null;
   }

   //---- does not match in AJDT, not invoked at runtime
  
   @Pointcut("get(@javax.persistence.PersistenceContext 
javax.persistence.EntityManager *.*) && args(em)")
   void entityManagerFieldGet_3(EntityManager em){}
      
   @Around("entityManagerFieldGet_3(em)")
   public EntityManager getEntityManager_3(JoinPoint jp, EntityManager em){
       System.err.println("****getEntityManager_3 em=" + em);
       return null;
   }

   //---- matches in AJDT, not invoked at runtime
  
   @Pointcut("get(@javax.persistence.PersistenceContext 
javax.persistence.EntityManager *.*) && this(em)")
   void entityManagerFieldGet_4(EntityManager em){}
      
   @Around("entityManagerFieldGet_4(em)")
   public EntityManager getEntityManager_4(JoinPoint jp, EntityManager em){
       System.err.println("****getEntityManager_4 em=" + em);
       return null;
   }

   //---- matches in AJDT, not invoked at runtime
  
   @Pointcut("get(@javax.persistence.PersistenceContext 
javax.persistence.EntityManager *.*) && @this(pc)")
   void entityManagerFieldGet_5(PersistenceContext pc){}
      
   @Around("entityManagerFieldGet_5(pc)")
   public EntityManager getEntityManager_5(JoinPoint jp, 
PersistenceContext pc){
       System.err.println("****getEntityManager_5 pc=" + pc);
       return null;
   }

   //---- matches in AJDT, not invoked at runtime
  
   @Pointcut("get(@javax.persistence.PersistenceContext 
javax.persistence.EntityManager *.*) && target(em)")
   void entityManagerFieldGet_6(EntityManager em){}
      
   @Around("entityManagerFieldGet_6(em)")
   public EntityManager getEntityManager_6(JoinPoint jp, EntityManager em){
       System.err.println("****getEntityManager_6 em=" + em);
       return null;
   }

   //---- matches in AJDT, not invoked at runtime
  
   @Pointcut("get(@javax.persistence.PersistenceContext 
javax.persistence.EntityManager *.*) && @target(pc)")
   void entityManagerFieldGet_7(PersistenceContext pc){}
      
   @Around("entityManagerFieldGet_7(pc)")
   public EntityManager getEntityManager_7(JoinPoint jp, 
PersistenceContext pc){
       System.err.println("****getEntityManager_7 pc=" + pc);
       return null;
   }


Also I only run with LTW'ing since I can't run it pre-compiled because 
ADJT is eating duplicate aop.xml/peristence.xml files in multiple 
eclipse output paths. Also because of this I haven't tried this with 
code style. I can peel this out of my larger project and create a small 
test case. But i you think you know the problem....  I suppose I can get 
the LTW'er spew out the weaved class file... I'll have to look up how to 
do that. Where whould you like me to send you the class file to?

thanks!
