Disclaimer

Moving to jackson 3 (and implicitly java 17) are maybe a real breaking change, I don't know the policy of maintainers about older java versions compatibilities, but well, I did this work for myself in first place, so at least you can take a look

Changes

• Bump java baseline to 17 in build.gradle + CI files (the minimum supported java version for jackson 3.x)
• Update gradle to 7.x (for java 17 support)
• Remove Java 8/11 tests because these versions are no longer supported by Jackson3.

From jackson3 migration guide (link bellow):

• Update Java package from com.fasterxml.jackson.[core/databind] -> tools.jackson.[core/databind]
• Replace removed ObjectCodec by the right implementation of ObjectReadContext/ObjectWriteContext interfaces (which are DeserializationContext and SerializationContext)
• JsonProcessingException -> JacksonException
• JsonGenerator.writeObject() -> JsonGenerator.writePOJO()
• JsonGenerator.writeFieldName() -> JsonGenerator.writeName()
• JsonNode.asText() -> JsonNode.asString()
• JsonNode.isTextual() -> JsonNode.isString()
• JsonParser.getCodec() -> JsonParser.objectReadContext()
