/**
* Designates an interceptor method that receives a callback when
* the target class constructor is invoked.
*
* The method to which this annotation is applied must have one of the
* following signatures.
*
*
*
* @AroundConstruct
* public void <METHOD>(InvocationContext ctx) { ... }
*
*
*
* @AroundConstruct
* public Object <METHOD>(InvocationContext ctx) throws Exception { ... }
*
*
* An AroundConstruct interceptor method may be only declared on an interceptor class.
*
* An interceptor class must not declare more than one AroundConstruct
* method.
*
* AroundConstruct methods may throw runtime exceptions,
* but not checked exceptions.
*
*
* 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 which
* constructor it interposes on.
