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.

Any news on the Classfile API?
Anyways, have you looked at Proguard core?

Resources for generating and execution JVM bytecode
For generating Java bytecode/class files you could take a look at ProGuardCORE . It's a bytecode manipulation and analysis library that grew out of ProGuard.

JEP draft: Classfile API
The MethodBuilder "low-level" example looks like the ProGuardCORE API for building classes & code sequences, which can be written as:

Show HN: I spent my vacation writing a modern JVM assembler
Something else that could make your code generation for your JVM language easier: ProGuardCORE (https://github.com/Guardsquare/proguard-core). It can be used to read, generate and analyse Java bytecode.
Some examples for code generation: ProGuard where the project originated (https://github.com/Guardsquare/proguard), Brainf*ck compiler (https://github.com/mrjameshamilton/bf), Lox compiler (https://github.com/mrjameshamilton/klox)
Disclaimer: I work at Guardsquare on ProGuardCORE so may be biased ;)

Looking for resources on building a compiler
I implemented Lox in Kotlin based on the book's Java interpreter then added a JVM backend using ProGuardCORE: https://github.com/mrjameshamilton/klox

Building a simple Log4Shell detector with ProGuardCORE
You can find out more about ProGuardCORE on GitHub and the manual contains some further examples.
-
Is there any books or guides on how to target JVM bytecode?
Not a book or guide but a useful library for working with/generating JVM class files is ProGuardCORE. It's the underlying library used by ProGuard and I also recently used it to add a JVM backend to my implementation of Lox from the Crafting Interpreters book.
-
Concise language to write an interpreter for?
After completing the first part of the book (using Kotlin instead of Java), I added a JVM backend using ProGuardCORE (https://github.com/Guardsquare/proguard-core).

AppSweep, mobile application scanning for developers
The biggest difference is our initial goal of creating a tool for application developers rather than a security team. This means we aim to exclude information that the application developer definitely knows and doesn't want to see again, e.g. the list of permissions an application is requesting. Furthermore we try to focus on nice and intuitive UX that is familiar to this audience, enabling an application developer to be very efficient in reading & interpreting the results (e.g. easy comparison of two builds). Also note that this is built on the same core technology as ProGuard. This foundation of compiler components (e.g. our partial evaluator) and the knowledge and experience at Guardsquare that comes with it will unlock many more in-depth code checks.

Reverse Engineering Tools in 2022
I think they forgot to google translate the disadvantages of JEB Decompiler
I haven't used JEB to comment, but I've gotten a lot of mileage out of https://github.com/pxb1988/dex2jar#readme and then feed the normal Java jars it produces into https://github.com/mstrobel/procyon#readme and (of course) one shouldn't overlook picking your favorite tool for dealing with AndroidManifest.xml which often has fun things hiding in it
While digging up those links, I was reminded that some folks enjoy https://github.com/Konloch/bytecode-viewer#is-there-a-demo because it can be easier to "try out" a few of the decompilation engines, but I don't use it because it's hard to do batch things with it, versus dex2jar into procyon is automation friendly

Is there any tool for Java reverse engineering that doesn't totally suck?
Here's a good tool for inspecting the bytecode of applications, with built in decompiler support: https://github.com/Konloch/bytecode-viewer

Stack Overflow Developer Survey: 54% of Respondents Dread Java?
If you're curious what anything (Lombok or otherwise) compiles to, JVM bytecode is much simpler than the kinds C/C++ compiles to. It's fairly readable even with the JDK disassembler javap. There are also various community disassemblers and decompilers that provide nicer output than javap. I use https://github.com/Konloch/bytecode-viewer, which is a GUI frontend for several. If one decompiler doesn't handle a class well, another usually does.

Looking for a lightweight java decompiler / code viewer that has dark mode
I use Bytecode Viewer, https://github.com/Konloch/bytecode-viewer with Dark Mode.

CandyPixel - Known Information Wanted Please.
if you do use this plugin i'd recommend also using https://bytecodeviewer.com/ to check the supposed malicious lines of code.

A response from r/AskReddit. Are we even surprised?
Take a look at tools like this one to get an idea of what you can actually get: https://bytecodeviewer.com/
- Needed some suggestions

1.8 source code
Also, you can always install the latest release and then put it through a Java decompiler to get the complete source code. It might have some errors since decompilers aren't perfect, but will give you a more complete source code than anything I can legally provide.
