pojo support for query / mutation parameter

[cryptoki]

up to version 5.x we could use our Java Pojos

public class SomeOldPojo {
  public String value;
}

  fun pojo(pojo: SomeOldPojo): String? = "hello ${pojo.value}"

query {
	pojo(pojo: {value: "abc"})
}

with the 6.x release the Jackson ObjectMapper is removed and therewith the java support. Is there a best practice to use / integrate old pojo?
