Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Introducing Astra: A Tool for Refactoring Java Programs at Scale
I wonder if type reference refactorings support more complex type migrations, where you'd like to migrate your code from type A to a similar type B with a different API, which involves rewriting the method invocations. Think, Guava Optional to j.u.Optional, or Joda Time Duration to j.t.Duration.

Any library you would like to recommend to others as it helps you a lot? For me, mapstruct is one of them. Hopefully I would hear some other nice libraries I never try.
error-prone is good for some extra static analysis.

How to use Java Records
A special kind of validation is enforcing that record fields are not null. (Un)fortunately, records do not have any special behavior regarding nullability. You can use tools like NullAway or Error Prone to prevent null in your code in general, or you can add checks to your records:

Why is `suspend` a language keyword, but @Composable and @Serializable are annotations
I am all in favour to more third side libraries adding functionalities, like Lombok, Manifold and error prone. As well as smaller projects like this shameless plug and what appears in this list

What does the future hold for Project Amber?
I haven't used it. I use Google's ErrorProne + Lombok to prevent NPEs in java.

Plans for Compile-time Null Pointer Safety?
Take a look at NullAway, a plugin for Error Prone.

What I miss in Java, the perspective of a Kotlin developer
For some of this stuff, there are compiler extensions that allow extra type checking to be added e.g. Google Error-Prone: https://github.com/google/error-prone with stuff like: https://errorprone.info/bugpattern/ReturnMissingNullable.
Doesn't help you with third party libraries, but across an org applying that rule (and others!) typically ensures some consistency.
