if i have a singleton declared with object syntax

object Foo { ... }

why is it still possible to read an instance of this "class" using jackson objectMapper with objectMapper.readValue(input, Foo::class.java) and then I can access fields from that.. Does this not violate the singleton?

it does but Jackson doesn't know that

there was an attempt to teach om.fasterxml.jackson.module.kotlin.KotlinModule but it turns out to break other parts of Jackson, https://github.com/FasterXML/jackson-module-kotlin/issues/281
