EE 6 and interceptors

[asookazian]

This is not directly related to Web Beans per se but I'm wondering why the EE 6 EG did not add a @BeforeInvoke and @AfterInvoke similar to what is available in Spring AOP.  I'm guessing it's because a simple @AroundInvoke is good enough in most cases.

Interception: Custom behaviour can be inserted before or after method invocations against any interface or class. This is similar to around advice in AspectJ terminology.

So what if you need more fine-grained control over when the interceptor is to be invoked?

And what are the interception options for Web Beans that are not EJB3 components?

Can't you do

  doWhateverBefore();
  invocationContext.proceed();
  doWhateverAfter();

in the interceptor or did I miss something?

Similar.
