I am able to attach my code into a target running jvm using the java.lang.instrument API with the agentmain() method. What next should I do if I want to get hold of a reference to all the available non-system (java.*) Objects? Can I just do a search of all the threads available and follows the reference recursively starting from the thread objects?

It seems to me that it would be better for me to instrument the classes by Javassist and modify their constructors so that whenever a new instance of the target class is created it will add a reference of itself to a global static data structure. (rather than having me to searching thru all the object reference recursively)

Would there be any tutorial available on using Javassist to modify the constructor of a class?
