Wrong and non-compilable condition (primitive result compared with null)

[ariannab]

Running Toradocu on class org.apache.commons.collections4.MultiMapUtils produces the following condition:

    "returnTag": {
      "comment": "true if the map is empty or null.",
      "kind": "RETURN",
      "condition": "args[0].isEmpty() ? (result == true||result==null)"
    },

This highlights 2 problems:

• a wrong translation, because it should be (((args[0]==null)==false) && args[0].isEmpty()) || args[0]==null ? result == true
• a missing check over the result type, because a primitive (boolean in this case) shouldn't be compared to null

The missing check over the result type (2nd problem) is solved by #226.

The current translation is: ((args[0]==null)==false) && (args[0].isEmpty()) ? methodResultID == true : methodResultID == false

Which is more correct than the original one, but it is still incorrect. Indeed, Toradocu fails to understand that the last part of the comment (or null) still refers to the map.
