Recipe IDorg.openrewrite.java.jackson.UseReadTreeAsValueInDeserializer

Artifactorg.openrewrite.recipe:rewrite-jackson

In Jackson 3, ObjectCodec is replaced by ObjectReadContext, which does not expose treeToValue. The equivalent method is readTreeAsValue(JsonNode, Class) on DeserializationContext. This recipe rewrites parser.getCodec().treeToValue(node, Foo.class) to ctxt.readTreeAsValue(node, Foo.class) inside methods that have a DeserializationContext parameter (typically JsonDeserializer.deserialize).
