How to Parse an Object with Unquoted Keys

It is very common to have unquoted keys in a JSON string, e.g.

{
name : "Jason",
age : 10
}

Other libraries, like Gson, handles this well, but on the Glassfish reference implementation this throws

```
Exception in thread "main" javax.json.stream.JsonParsingException: Unexpected char 97 at (line no=2, column no=8, offset=13), expecting 'u'
