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<>();

map.put("recursive",map);

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

• Immutables

  6 3,373 6.6 Java

  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 included

  

Project 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 [1] is a library that does it using bog standard annotation processing rules that don't require hacking your build process.

Project mention: Scala Custom JSON codec Help | /r/scala | 2023-06-05

The other comment is asking the right questions. But also how is it failing? Do you have an error message? Is JsonUtil part of Jackson? Do you need to be using https://github.com/fasterxml/jackson-module-scala with an object mapper?

• jackson-jq

  2 271 5.1 Java

  jq for Jackson Java JSON Processor

Project 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.
