Double. NEGATIVE_INFINITY parses to string but fails to serialize back to a double

[timlevett]

Hi, see failing test below

  @Test
  public void testInfinity() {
    String serializedString = JsonStream.serialize(Double.NEGATIVE_INFINITY);
    Double deserializedInfinity = JsonIterator.deserialize(serializedString, Double.class);

    assertTrue(deserializedInfinity == Double.NEGATIVE_INFINITY);
  }

Including error
