    String s = "m\\"+"/m\\/m/m/m/m/m";

    LinkedHashMap<String, String> hm = new LinkedHashMap<>();

    hm.put("test", s);

    System.out.println(hm+"  Hash map = "+hm.toString());

Fine Output is {test=m\/m\/m/m/m/m/m} Hash map = {test=m\/m\/m/m/m/m/m}

    String s2 = new Gson().toJson(hm.toString());

    System.out.println("Json result is "+s2);

Not Fine Output is Json result is "{test\u003dm\\/m\\/m/m/m/m/m}"

Is GSON going mad or is it something that I am doing wrong? What is happening to with Back Slashes and from where does this u003d appears? I knew that there exists a bug of this nature a long time ago but it was resolved. How can I resolve this issue? Thanks in advance.

The = sign is encoded to \u003d. Hence you need to use disableHtmlEscaping().

You can use 

Gson gson = new GsonBuilder().disableHtmlEscaping().create();
String s2 = gson.toJson(hm.toString());

For \/ turning into \\/ issue, the solution is 

s2.replace("\\\\", "\\");
