I'm not sure if that is a good enough argument for keeping the non-bytecode-instrumentation solution, though. Or if we could replace the non-bytecode-instrumentation solution with an updated bytecode instrumentation solution in a later update? Not ideal, but would allow us to complete the project on time.

The original plan was for the code in this review to go into both 8 and 7u12. Since 7u12 has a tighter deadline, a possible path would be to include it only in 7u12, but not in 8. For 8 we would then implement a fully dynamic solution. The only thing needed in 8 from this review would be the path field added to the stream classes. Does that sound like a plan?
