Election for Devin Papineau as Committer on Eclipse OpenJ9

Devin Papineau 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 (for example, method inlining, value propagation, idiom recognition, and the symbol validation manager). He is well-versed in many areas of the Java Virtual Machine Specification and has been deeply involved in the JIT’s design, experimentation, and implementation of JEP 169 (Value Objects) and MethodHandles (both OpenJ9 and OpenJDK).

Devin has contributed 69 pull requests (and 114 commits) to the project, and has repeatedly demonstrated thoroughness in his implementation and quality assurance of each of those commits. He also monitors and provides responses to questions asked on the Eclipse OpenJ9 Slack workspace, particularly in areas dealing with the compiler, optimizations, or compiler IL.

One of Devin’s invaluable strengths is the thoroughness of his code and design reviews. He has formally reviewed 67 PRs but has been indirectly involved in shaping many others. His reviews draw upon his deep experience with the common optimizer, Testarossa IL design and operation, optimization theory, the Java VM specification, C++, and debugging techniques. He often discovers missed corner cases and design limitations, and articulates his observations through clear examples and sample Java code when appropriate. His review comments are provided in a timely fashion and always reflect professionalism and respect for contributors.

I believe Devin will be an excellent committer on the Eclipse OpenJ9 project.
