OutOfMemoryError when parsing an invalid JSON

[cvrabie]

This seems to happen in 1.3.0.

scala> val s = """{"a":"B","c:789}"""
s: String = {"a":"B","c:789}

scala> s.parseJson

  ... 18 elided

Note that the quote from the second field name (c), is not closed correctly. However I would expect a spray.json.JsonParser.ParsingException or a spray.json.DeserializationException instead.

Oops. This indeed looks like a major bug! We'll need to get that fixed quickly.
