[openj9-dev] Committer Election for Henry Zongaro on Eclipse OpenJ9™ has

[emo@xxxxxxxxxxxxxxxxxxxxxx]

A committer election for Henry Zongaro on project Eclipse OpenJ9™
(technology.openj9) was started by Daryl Maier with this criteria:

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.
