# ADR-0002 - Avoid using Java serialization

## Status

- ACCEPTED on 2023-12-01

## Context

In Gradle we often need to serialize in-memory objects for caching, or to transmit them across process barriers, etc.
Java serialization is one way to implement this, however, despite its simplicity of implementation, it has several drawbacks:

- **Performance:**
Java's built-in serialization mechanism is often slower compared to other serialization solutions.

Elle inclut des moyens de s'authentifier en utilisant un « tiers ».

C'est ce que tous les systèmes avec « connexion avec Facebook, Google, X (Twitter), GitHub » utilisent en arrière-plan.

### OAuth 1 { #oauth-1 }

Il y a eu un OAuth 1, très différent d'OAuth2, et plus complexe, car il incluait des spécifications directes sur la manière de chiffrer la communication.
