General data-binding package for Jackson (2.x): works on streaming API (core) implementation(s)Project mention: The Bogus CVE Problem | news.ycombinator.com | 2023-09-21
Jackson had this problem a few months back, where someone reported a critical CVE against the project and broke builds all around the planet https://github.com/FasterXML/jackson-databind/issues/3972
Basically the programmer (not the attacker) had to write code where an object contained itself
HashMap map=new HashMap<>();
After this, Jackson would indeed stack overflow if you asked it to wrap the object to JSON. Then again, half the build-in Java functions (e.g. getting an object hashcode for the map object) also fail for a recursive structure.
The issue remains open 3 months later, Mitre still thinks it's hella serious, and people have yet again learned to just ignore their CI warning about CVEs
Annotation processor to create immutable objects and builders. Feels like Guava's immutable collections but for regular value objects. JSON, Jackson, Gson, JAX-RS integrations includedProject mention: Unchecked Java: Say Goodbye to Checked Exceptions Forever | news.ycombinator.com | 2023-07-13
This is every Lombok lover's favorite strawman argument I've run into.
I've been coding in Java professionally for ~20 years. I can count with zero hands the number of times I've been burned by a getter or setter getting changed into something surprising.
If you really need auto-generated getters/setters/builders - Immutables  is a library that does it using bog standard annotation processing rules that don't require hacking your build process.
Core part of Jackson that defines Streaming API as well as basic shared abstractions
Generates TypeScript from Java - JSON declarations, REST service client
JSON query and transformation languageProject mention: FLaNK Stack Weekly for 24April2023 | dev.to | 2023-04-25

Uber-project for (some) standard Jackson textual format backends: csv, properties, yaml (xml to be added in future)
jq for Jackson Java JSON ProcessorProject mention: jq 1.7 Released | news.ycombinator.com | 2023-09-06
So just picking Java https://github.com/eiiches/jackson-jq
> jackson-jq aims to be a compatible jq implementation. However, not every feature is available; some are intentionally omitted because thay are not relevant as a Java library; some may be incomplete, have bugs or are yet to be implemented.
Where JMESPath has fully compliant 1st party implementations in Python, Go, Lua, JS, PHP, Ruby, and Rust and fully compliant 3rd party implementations in C++, Java, .NET, Elixer, and TS.
Having a spec and a test suite means that a all valid JMESPath programs will work and work the same anywhere you use it.
Extension module to properly support datatypes of javax.money
Unconventional Java code for building web servers / services without a framework. Think dropwizard but as a seed project instead of a framework. If this project had a theme it would be break the rules but be mindful of your decisions.
⚗️ Lightweight HTTP extensions for JavaProject mention: 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. | /r/java | 2023-05-27

Simplified polymorphic de/serialization of Java 17 sealed classes for JacksonProject mention: Rust like Enums in Java | /r/java | 2023-05-02
