Jackson3 Changes

Proposed Jackson 3.0 API changes

JVM/JDK Compatibility

• Jackson 3.x will require and be based on Java 8
  • with possible exception of jackson-core and jackson-annotations (?)

Module structure

• Embed some/all Java8 modules
  • Embed "parameter names", "datatypes" (Optional)
  • Need to think of Java 8 date/time module (size)

API Entities to deprecate/remove/embed

• ContextualSerializer / ContextualDeserializer, ResolvableSerializer/ResolvableDeserializer`
  • just embed as part of JsonSerializer / JsonDeserializer, with no-op implementation

Major API change areas:

• JsonNode needs major rework; can do binary-incompatible return value changes

Changes to defaults

(will require wiki sub-page)

• DeserializationFeature
  • FAIL_ON_UNKNOWN_PROPERTIES: change default to false?
• Other
  • Check defaults of date/time handling

Features to Remove

Jackson-core: Format Auto-Detection
