Election for Henry Zongaro as Committer on Eclipse OpenJ9

Henry Zongaro has been an active contributor to the Eclipse OpenJ9 project since 2017.

He is articulate in the design and operation of many optimizations in the common optimizer in the JIT compiler and the theory behind them. In particular, Henry is a recognized expert in the escape analysis and value propagation optimizations that are vitally important for performance on many Java workloads. His comprehensive Escape Analysis vitality talk [1] is the most popular OpenJ9 vitality talk to date. Henry has been leading the JIT’s design, experimentation, and implementation of JEP 169 (Value Objects) ensuring not only functional correctness but minimizing the performance impacts as well. Henry draws on many years of experience with not only the JIT but on different compiler technologies, hardware platforms, optimizations, operating systems, programming language design, benchmarking, Java middleware stack products (such as WebSphere), and performance analysis techniques.

Henry has contributed 67 pull requests [2] (and 94 commits) to the project and has repeatedly demonstrated thoroughness in his implementation and quality assurance of each of those commits. He is a regular participant in the weekly OpenJ9 Community Call, and he monitors and provides responses to questions asked on the Eclipse OpenJ9 Slack workspace particularly in areas dealing with performance, escape analysis, value propagation, or value objects.

One of Henry’s strengths is the thoroughness and thoughtfulness of his code and design reviews. He is able to explain complex topics clearly which is greatly valued by contributors seeking reviews from him. He has formally reviewed 38 pull requests [3] and has been indirectly involved in shaping many others. His review comments are provided in a timely fashion when requested and always reflect professionalism and respect for other contributors.

I believe Henry is a deserving committer for the Eclipse OpenJ9 project.
