Interceptors invocation sequence?

Hi ranchers,
I was trying out some features of the EJB Interceptors and came to a strange behavior:

Statefull session bean defines class interceptor.
Upon calling a method, first is fired the class interceptor, and then the method itself (this is normal).
Console output:

Once I added @PostConstruct to the session bean and to the ClassInterceptor I got the following (normal) behavior:

Now for the weird part: I add a @PostConstruct method in the MethodInterceptor, which is assigned to a *totally* different method from the one being called in the session bean, and I get the following (non-normal?) behavior:

No interceptors are defined in ejb-jar.xml

My Bean code:

ClassInterceptor (MethodInterceptor is identical, just a different .java)

The client:

My question is: why is @PostConstruct on the MethodInterceptor called? It's associated with a method that is not even called at all (demostrated by it's @AroundInvoke method non being called).

Any ideas?



Edited: forgot to add: using JBoss 4.0.5

It kind of reminds me of the joke.

Man goes into the doctor's office and raises his hand and arm above his head and says "Doctor it hurts when I do this". Doctor says, "Then don't do that"
