Hi Eliot, Thanks for the suggestion; from inspecting the java agent capability, I see that I can use it to instrument the source code (and modify the object). However, I need an ability to listen to vm events (such as when a object is created and collected) and modify the object header of an object. Therefore, I found Jike more suited to my purpose. Please kindly correct me if I am wrong. Thanks again for the feedback, I really appreciate it.
