Failure to serialize enums with method definitions.

I've attached a JUnit test file that shows the issue. I've confirmed that the 
following patch fixes this.

Existing method in Gson.java:

  public String toJson(Object src) {
    if (src == null) {
      return serializeNulls ? NULL_STRING : "";
    }
    return toJson(src, src.getClass());
  }

Patched version of above method:

  public String toJson(Object src) {
    if (src == null) {
      return serializeNulls ? NULL_STRING : "";
    }

    Type typeOfSrc;
    if (src instanceof Enum) {
      typeOfSrc = ((Enum) src).getDeclaringClass();
    } else {
      typeOfSrc = src.getClass();
    }

    return toJson(src, typeOfSrc);
  }
