Not able to use JSON Path for json attributes having space

[GoogleCodeExporter]

What steps will reproduce the problem?
I have a json in following format where the json property 'All Categories' has 
a space in the middle:
{
  "All Categories": {

    "color": "#0adc00",
    "name": "Category Main",
    "data": [
      {

        "color": "#00dc00",
        "name": "Sub Category 1",
        "comments": 13,
        "data": [
          {

            "color": "#00dc00",
            "name": "Sub Sub Category",
            "comments": 8,

          },
 ],

        "tagColor": "0X00dc00"
      },
 ],
    "comments": 59,
    "tagColor": "0X0adc00"
  },
 }
}

When i use the following json path expression in my code to get the data nodes
[All Categories].data 

Following exception is shown:
-----------------------------

java.lang.IllegalArgumentException: Invalid JSON expression:
Script1.groovy: 1: unexpected token: [ @ line 1, column 27.
                            [All Categories].data
                             ^

I also tried with following JSON Path expression which also didn't work:
All Categories.data 

Exception thrown for this instance is

By using "\"All Categories\".data" i am able to get the nodes. This solution 
was given in https://code.google.com/p/rest-assured/issues/detail?id=318

Yeah you need to escape the path if they contains space. It's a bit more 
readable if you use single quotes:

"'All Categories'.data"
