JSONPatch escape slash '/' from JSONPatch+JSON

I've below JSON and I wanted to update few fields from it

{
        "process": "my-process",
        "pod": "some-pod",
        "org": "some-org",
        "config": {
            "version": "436_601_83.0.0",
            "path": "companyName/ccg",
            "description": "update the version",
            "dependencies": null
        }
}

using postman PATCH API call with below JSONPatch payload API is working fine

[
    {
        "path": "/config/version",
        "op": "replace",
        "value": "436_605_83.0.0"
    },
    {
        "path": "/config/description",
        "op": "replace",
        "value": "foo bar"
    }
]

But, I want to implement same using Java .. I tried

JsonPatch jsonPatch = new JsonPatch(
                        Arrays.asList(               
                           new ReplaceOperation(JsonPointer.of("/config/version"),
                              new TextNode("436_605_83.0.0"))
                        )
                );

It evaluates to :

[{"op":"replace","path":"/~1config~1version","value":"436_605_83.0.0"}]

This doc mentioned that http://jsonpatch.com/#json-pointer we MUST use escape the characters with ~0 and ~1 but no luck yet, I escaped / using ~1 i.e. "~1config~1version" but it evaluates to "/~01config~01version"

I think the problem is in the JsonPointer definition. Please, try something like that instead:

JsonPatch jsonPatch = new JsonPatch(
  Arrays.asList(               
    new ReplaceOperation(
      // Note we should provide the different paths tokens here
      JsonPointer.of("config", "version"),
      new TextNode("436_605_83.0.0")
    )
  )
);

Or, equivalently:

JsonPatch jsonPatch = new JsonPatch(
  Arrays.asList(               
    new ReplaceOperation(
      // Create the JsonPointer with the full path
      new JsonPointer("/config/version"),
      new TextNode("436_605_83.0.0")
    )
  )
);

Please, see this test, it provides guidance about how to tactically build JsonPointers and the meaning of escaping reserved chars.
