[jboss-user] [EJB 3.0] - Exception with AroundInvoke

[peiguo]

I wrote a Profiler with AroundInvoke, and here is the code:
import javax.interceptor.*; 
  | import javax.ejb.*;
  | 
  | public class Profiler 
  | {
  | 	public Profiler() {
  | 	}
  | 
  | 	@AroundInvoke
  | 	public Object profile(InvocationContext ctx) throws Exception  
  | 	{
  | 		System.out.println("there");
  | 		long t1 = System.currentTimeMillis();
  | 		try
  | 		{
  | 			return ctx.proceed();
  | 		}
  | 		finally
  | 		{
  | 			long t2 = System.currentTimeMillis() - t1;
  | 			System.out.println(ctx.getMethod().getName() + 
  | 			 "(" + ctx.getParameters()[0] + ") took: " + 
  | 			 ((t2 - t1)/ 1000.0) + " ms");
  | 		}
  | 	}
  | }
  | 

I used it to annotate a class like this:
	@Interceptors ({Profiler.class})

When I invoke the EJB, I got this:
