Seam and multiple occurrences of same exception in server.log

[asookazian]

I've noticed that there are multiple attempts at the same business method call if the method throws an exception.

For example:

@Name("jmxHibernateStatistics")
public class JmxHibernateStatistics {...}

@Name("myTest1")
@Scope(ScopeType.CONVERSATION)
public class TestApplicationMetaDataAction {

   @In
   private JmxHibernateStatistics jmxHibernateStatistics;

   @Create
   public void init(){
     jmxHibernateStatistics.foo();
   }
}

I see NullPointerException several times in the server.log which indicates that the init() method was executed several times (and I know this is the case b/c I placed a debug breakpoint in the foo() line).

If I add @AutoCreate to the JmxHibernateStatistics class, then the init() method is called just once.

So why does JBoss and/or Seam (or whatever it may be - interceptors?) call the init() method so many times in the first case???

as a side note, you'd think the injection would fail b/c I didn't have create=true for the @In or @AutoCreate in the first scenario...
