[Jboss-dev-forums] [Design of AOP on JBoss (Aspects/JBoss)] - Infinite loop when applying caller aspects

[oberon777 <nu...@jb...>]

I have been using caller aspects successfully until it came to instrumenting calls to some Swing classes. 

In particular, the method I am instrumenting is javax.swing.JTable->addNotify. The interceptor method looks as follows:


  |     public Object invoke(Invocation invocation) throws Throwable {
  |         //        log.println("Hit " + invocation);
  | 
  |         if(invocation instanceof CallerInvocation){
  |             CallerInvocation cinvocation = (CallerInvocation)invocation;
  | 
  |             process_call(cinvocation);
  |         }else{
  |             System.err.println("Unexpected " + invocation);
  |         }
  | 
  |         try{
  |             return invocation.invokeNext();
  |         }finally{
  |             //System.err.println("Failed...");
  |         }
  |     }
  | 

and the problem is that the return statement invocation.invokeNext causes method invoke() to be called on the same method as before leading to an infinite loop.

Any thoughts?
