/**
* Defines an interceptor method that interposes on business methods.
* The method must take a single parameter of type
* {@link javax.interceptor.InvocationContext} and have a return type
* {@link java.lang.Object}. The method must not be declared as abstract,
* final, or static.
*
*
* @AroundInvoke
* public Object intercept(InvocationContext ctx) throws Exception { ... }
*
*
* AroundInvoke methods may be declared in interceptor
* classes, in the superclasses of interceptor classes, in the target
* class, and/or in superclasses of the target class.
*
* A given class must not declare more than one AroundInvoke
* method.
*
* An AroundInvoke method can invoke any component or
* resource that the method it is intercepting can invoke.
*
* In general, AroundInvoke method invocations occur within the
* same transaction and security context as the method on which they are
* interposing.
*
* AroundInvoke methods may throw any exceptions that are
* allowed by the throws clause of the method on which they are
* interposing. They may catch and suppress exceptions and recover
* by calling {@link javax.interceptor.InvocationContext#proceed()}.
