Hi,
I am a Committer of the JDK project in the OpenJDK Community so I am very familiar to the new version of the OpenJDK, especially 17. Most of my patches, which were integrated to the JDK, is about Javac (The Java compiler, including the parser) so I have the advanced skill to implement the parser.
I read your desciption and found that your project is very suitable to me. I will provide the better code and good communication experience for you.
Best Regards,
