Serializing or de-serializing a property called 'this' might be 
problematic for a Java or JavaScript object ?

There is some precedent for using 'self'.

It is part of the Atom syntax.
https://tools.ietf.org/html/rfc4287#section-4.1.1

     "atom:feed elements SHOULD contain one atom:link element with a
      rel attribute value of "self".  This is the preferred URI for
      retrieving Atom Feed Documents representing this Atom feed."

It is also used in the Spring HATEOAS implementation.

     {
     "name": "Alice",
     "links": [ {
         "rel": "self",
         "href": "http://localhost:8080/customer/1"
         } ]
     }
