Observing Project Valhalla, Cay Horstmann

This talk focuses on Project Valhalla, which introduces value types into the Java language and virtual machine. The speaker discusses the potential efficiency gains from value types, which eliminate the need for pointer indirection and heap allocation, while also aiming to create a more consistent object model. Attendees will explore the current state of the project and learn how to monitor Valhalla's behavior using tools such as JMH benchmarks, Java Flight Recorder, JITWatch, and the Java Object Layout tool. By the end of the session, participants will be equipped to assess the impact of Valhalla on their Java workloads.
