Elasticsearch: Error when trying to define an absolute path for synonyms/stopwords file.

This is the error I am getting: reason=access denied ("java.io.FilePermission" "E:\elasticsearch\synonyms\synonyms.txt" "read")

Now, I know the message is really specific about the problem, there's only one problem... that folder and file have literally no security restrictions, I open the file permissions to everyone, and I'm still getting the same error.

Is this an error, or what am I doing wrong here? O.o

This is the request I am sending

{  
    "settings":{ 
        "analysis":{  
            "analyzer":{  
                "standard":{  
                    "tokenizer":"standard",
                    "filter":[  
                        "lowercase",
                        "asciifolding",
                        "standard",
                        "synonyms"
                    ],
                    "type":"custom"
                }
            },
            "filter":{  
                "synonyms":{  
                    "synonyms_path":"E:\\elasticsearch\\synonyms\\synonyms.txt",
                    "ignore_case":true,
                    "type":"synonym"
                }
            }
        }
    }
}

By the way, I'm using Windows Server 2012 here
There you have the file permissions' settings right now for the file.

My ES version is 2.2.0
JVM version: 1.8.0_65
OS version: Windows Server 2012

Also, here you have the log information, just in case you found it useful:
