/**
* Designates an interceptor method that receives a callback when
* the target class constructor is invoked.
*
* The method to which the AroundConstruct annotation is applied must have one of the
* following signatures.
*
*
*
* void <METHOD>(InvocationContext ctx)
*
* Object <METHOD>(InvocationContext ctx)
*
*
* The method must not be declared as abstract, final, or static.
*
* An AroundConstruct interceptor method may be only declared in
* an interceptor class or superclass of an interceptor class.
*
* An interceptor class must not declare more than one AroundConstruct
* method.
*
* The target instance is created and its constructor injection is
* performed, if applicable, when the last interceptor method in the
* AroundConstruct interceptor chain invokes the
* {@link javax.interceptor.InvocationContext#proceed()} method.
*
*
An AroundConstruct interceptor method should exercise caution
* accessing the instance whose constructor it interposes on.
*
* AroundConstruct methods may throw any exceptions that are
* allowed by the throws clause of the constructor on which they are
* interposing.
