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?

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
