Thanks a lot for the response, Toby! It is very helpful. I hope you can answer these couple of question about your comments: 1) "you can look for the putfield and putstatic instructions" Q. I was going to look for ALOAD instructions to spot where variables get loaded onto stack - you suggest "putfield" and "putstatic" instead of that ? 2)"but that won't catch any modifications that occur through reflection." Q. So, is there any way at all to find instructions related to modification of variables through reflection? 3) Can you suggest some code examples or open source tools that do something similar to what my task is? - I am trying to modify classfile, but not at the run time. Thanks a lot! Vicki

If it did, you could try to scan for store instructions. Second, you can look for the putfield and putstatic instructions to see when instance and static variables are modified, but that won't catch any modifications that occur through reflection.
