> {code:java}
> select get_json_object('{"1": 5}', '$.1');
> {code}
> returns error:
>  
> {code:java}
> "Expected key at position 2"
> {code}
>  
> I guess it's caused by using function FindEndOfIdentifier that expects first symbol of key to be a letter.
> Hive version of get_json_object works fine in this case.
