Answer 1

Intercepting method calls (including constructors) without changing a ton of existing code is one thing Aspect-oriented programming was made for.

Check out AspectJ for a start.

With AspectJ, you can define a "pointcut" that specifies that you want to intercept constructor calls for a certain object or set of objects (using wildcards if need be), and within the interception code ("advice"), you will be given method context, which includes information about the both the calling method and object.

You can even use AspectJ to add fields to your object's to store the parent reference without modifying their existing code (this is called "introduction").
