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.

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/

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.

New open source Java decompiler
Hello! Today I'm happy to announce the release of a project that me and my friends have been working on over the course of the last year, Quiltflower! Originally intended just for use with the QuiltMC toolchain with Minecraft, Quiltflower quickly expanded to be a general purpose java decompiler aiming to create code that is as accurate and clean as possible. If the name sounds familiar it's because Quiltflower is a fork of Fernflower, the (in)famous decompiler that was developed by Stiver, maintained by Jetbrains, and became the default decompiler in Intellij IDEA. Fernflower also quickly found its way into many other tools. After many frustrations with it myself with its decompiled code structuring and quality I decided to do something about it, and here we are! Over the past year, Quiltflower has added support for features such as modern string concatenation, a code formatter, sealed classes, pattern matching, switch expressions, and try-with-resources, and more. Quiltflower also focuses on the code quality of the decompiled output, and takes readability very seriously. We'd greatly appreciate it if you'd give it a try, with our Intellij Plugin or as a standalone jar. While it has come a long way it's still a work in progress, and feedback can be reported on our issue tracker.

Visually Edit Decompiled Class File?
You can decompile the classes into .java sourcecode using Fernflower and store that to disk, then use the Attach Sources option to add it to the binary dependency you're using. This allows you to edit the source freely for your reference while continuing to use the original binary.
