Very Java-esque name for the largest Java project there is. I like it.
"Eclipse AdoptOpenJDK Adoptium" has a good ring to it. Reminds me of the SharedSessionContractImplementor I worked on last week for our Hibernate interface.
I feel like the new name doesn't reflect what this project is about. "Eclipse Adoptium" is too abstract, and sounds like a Eclipse feature. I think that just adding Eclipse as a prefix would have been easier.
