[Jboss-dev-forums] [Design of AOP on JBoss (Aspects/JBoss)] - StackOverflow when trying to

[nthx <nu...@jb...>]

Hi there!
I need help cause I cannot figure it out by myself. I got stackOverflow and don't know why... Here's the short code

public void test(){
  |     TestRoot root = new TestRoot();
  |     ((Persistable)root).getObjectByOID(id);
  | }

Output:
    [junit] Testcase: testGetObjectByOID took 4,575 sec
  |     [junit] 	Caused an ERROR
  |     [junit] null
  |     [junit] java.lang.StackOverflowError

  |     [junit] 	at org.nthx.pat.tests.TestRoot.getObjectByOID(TestRoot.java)
  | ......and so on..
  | 


My configurations:

<introduction expr="class(@pat.root)">
  |     <interfaces>
  |         org.nthx.pat.Persistable
  |     </interfaces>
  | </introduction>
  | <bind pointcut="call(void $instanceof{org.nthx.pat.Persistable}->getObjectByOID(java.lang.Long))">
  |     <advice aspect="org.nthx.pat.PersistableAspect" name="getObjectByOID"/>
  | </bind>
  | 
  | @pat.root
  | public class TestRoot{}
  | 
  | public interface Persistable
  | {
  |     public Identifiable getObjectByOID(Long OID);
  | }
  | 
  | public class PersistableAspect
  | {
  |     public Object getObjectByOID(Invocation invocation) throws Throwable
  |     {
  |         return null;
  |     }
  | }

Any idea would be appreciated, cause I really don't know why is this happening. I see nothing making the loop ...

Is it becase I cut a nonexistent method? There is no mixin here..

Regards,
Tomasz
