OpenJDK Development and Optimization at Google

Explore OpenJDK's implementation at Google in this 44-minute talk by Jeremy Manson. Gain insights into Java development practices, deployment challenges, and static analysis techniques employed by Google. Discover why coders initially resist static analysis and how they come to appreciate its benefits. Learn about global changes, non-build breaking errors, and dynamic analysis approaches. Understand the limitations of traditional profiling methods and delve into garbage collection optimization strategies. Examine experimental stack allocation techniques and their potential impact on Java performance at Google.
