absent properties sets to zero for primitives by default

Describe your Issue

When we use constructor injections
record DTORecord(int id) {}
with empty body request {} it should be consider as bad request, property id is mandatory.
What is the reason to consider absent value as zero? Zero is a value, why does framework decides for me which value I send?
Am I missing some logic?
so why FAIL_ON_MISSING_CREATOR_PROPERTIES is not a default behavior?

If you want it to be required, use @JsonProperty(required=true) or enable FAIL_ON_MISSING_CREATOR_PROPERTIES.

As to why default of 0: this is the default value for ints (if you leave a POJO int field unassigned it'll have that value) -- since something must be passed, Jackson uses what is generally considered the default (since null won't work for primitives).
For historical reasons properties in Jackson are considered optional.
If your preference is different, use configuration.
