Well to clarify on what I meant...
In the JsonSlurper class, 'parse' DOES output to an OBJECT
java.lang.Object *parse
<https://javadoc.io/static/org.codehaus.groovy/groovy-all/2.0.2/groovy/json/JsonSlurper.html#parse(java.io.Reader)>*
(java.io.Reader reader)
java.lang.Object parseText
<https://javadoc.io/static/org.codehaus.groovy/groovy-all/2.5.3/groovy/json/JsonSlurper.html#parseText-java.lang.String->
(java.lang.String text)
... which can (and usually is), sent to a JsonObject for ease of use.
Secondly, I say static in the fact that you don't need to instantiate
JsonSlurper to use the methods:
def object = JsonSlurper.parseText('{ "name": "John Doe" }
This works just fine.
