Update array element using JsonPath - arrays

Question

I am trying to replace a certain element in an a Json array using jayway's JsonPath in Java. Example:
{
"store": {
"book": [
{
"category": "reference",
"author": "Nigel Rees",
"title": "Sayings of the Century",
"price": 8.95
},
{
"category": "fiction",
"author": "Evelyn Waugh",
"title": "Sword of Honour",
"price": 12.99
},
{
"category": "fiction",
"author": "Herman Melville",
"title": "Moby Dick",
"isbn": "0-553-21311-3",
"price": 8.99
},
{
"category": "fiction",
"author": "J. R. R. Tolkien",
"title": "The Lord of the Rings",
"isbn": "0-395-19395-8",
"price": 22.99
}
],
"bicycle": {
"color": "red",
"price": 19.95
}
},
"expensive": 10
}
Here I'd like to be able to replace the first book in the array. I can find the element by using this query $.store.book.[?(#.author =='Nigel Rees')]
I then use this code to replace the this node:
Configuration configuration = Configuration.builder()
.jsonProvider(new JacksonJsonNodeJsonProvider())
.mappingProvider(new JacksonMappingProvider())
.build();
DocumentContext pbContext = JsonPath.using(configuration).parse(theAboveJson);
pbContext.set("$.store.book.[?(#.author =='Nigel Rees')]", someOtherJson);
But I noticed that instead of replacing, the new node is inserted at position 0 in the books array. Is there any way to actually replace the array element?
