      In Javascript (and probably any other untyped scripting language), there is no way to set a JSON property to null using Spin. For example, this fails:

      node = S(input, "application/json");
node.prop("order", null);

      with the error:

      Can't unambiguously select between fixed arity signatures [(java.lang.String, org.camunda.spin.json.SpinJsonNode), (java.lang.String, java.lang.Boolean), (java.lang.String, java.lang.String), (java.lang.String, java.util.Map), (java.lang.String, java.util.List), (java.lang.String, java.lang.Number)] of the method org.camunda.spin.impl.json.jackson.JacksonJsonNode.prop for argument types [java.lang.String, null]

      Apparently, some scripting engines have more or less ugly extensions to explicitly select a method. For example, in Nashorn, the problem can be worked around as follows:
      node["prop(String, String)"]("order", null);
