Author

Version history

2024-12-01: Created first version

Status

Being discussed; some implementation

Overview

During Jackson 2.x, some Modules have become unnecessary either in general, or for future use. For example:

jackson-module-paranamer module (part of jackson-modules-base was useful before Java 8, but it becomes unnecessary with Java 8 when JDK bytecode can contain parameter names

Other modules have become unsupported/unmaintained:

jackson-module-jsonSchema:
- Has no active maintainer
- Only supports older JSON Schema v3 (which is incompatible with newer schema versions)
- Has become obsolete due to existence of other maintained, external JSON Schema generators
