Any help?

I think it would help if you described what you're trying to achieve, rather than the current stumbling block.[0]

Reading between the lines then it seems you're trying to add some kind of adhoc allocation profiling, so I wonder if you've seen the Low Overhead Heap-Profiling work that went into jdk/jdk just a few weeks ago?[1]

If it doesn't fit your use-case - or you really need something like it applied to JDK 9 - it might still be good advice to study the code and approach taken there before reverse-engineering the entire OpenJDK source code... :-)
