/**
* 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 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.
*
*
* @since Jakarta Interceptors 1.2
