/**
* Defines an interceptor method that interposes on business methods. The method must take a single parameter of type
* {@link 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 InvocationContext#proceed()}.
