Description

      def builder = new groovy.json.JsonBuilder()
        def root = builder.people {
            firstName 'Guillame'
            lastName 'Laforge'
            married true
            conferences 'JavaOne', 'Gr8conf'
            blank ''
        }
        println builder.toString()
        println builder.toPrettyString()

        String s = '""'
        println "$s"
        println "${s[1..-2]}"
        println "${StringEscapeUtils.escapeJava(s[1..-2])}"

output

{"people":{"firstName":"Guillame","lastName":"Laforge","married":true,"conferences":["JavaOne","Gr8conf"],"blank":""}}
{
    "people": {
        "firstName": "Guillame",
        "lastName": "Laforge",
        "married": true,
        "conferences": [
            "JavaOne",
            "Gr8conf"
        ],
        "blank": "\"\""
    }
}
""
""
\"\"

I think there is a bug on file "D:\groovy-src-2.0.4\groovy-2.0.4\subprojects\groovy-json\src\main\groovy\groovy\json\JsonOutput.groovy"

line 190-192

     } else if (token.type == STRING) {
                output.append('"' + StringEscapeUtils.escapeJava(token.text[1..-2]) + '"')
