For engineers, architects, and DevOps teams, distributed architectures and reactive applications make pinpointing and fixing production errors in Java and Scala code an increasingly difficult task. In this hands-on, practical video, JVM and debugging expert Tal Weiss reviews the practices Java and Scala developers can use to spot, profile and correct production application issues. He provides a set of advanced techniques that can be put to immediate use for quickly profiling and debugging live servers, and resolving critical errors without impacting performance.

Extremely good presentation from Tal Weiss. I downloaded the code and it worked out of the box. It is just complex enough to show the capabilities of instrumentation and can serve as a good base for your own bytecode engineering needs.
Tal did a very good job in showing various techniques to debug live production code. The biggest part (on instrumention) is the best I've ever seen. And it's fun to listen to him! Thank you Tal.
Bottom Line Yes, I would recommend this to a friend
