Java Date to String without suffix timezone

Question

I've created the function below:

public static String marshalDate(Calendar value) {
    if (value == null) {
        return null;
    } else {
        DateFormat date = new SimpleDateFormat("yyyy-MM-dd");
        String format = date.format(value.getTime());
        return format;
    }
}

The input will be Calendar, the string value is: 2014-10-17 00:00:00.000000

The expected result after running the function above should be:

2014-10-17

it works properly when I deploy the spring boot application locally and hitting the API on local.

But when deploying the spring boot application on AWS, and I was hitting the API from local, the value that I received is: 2014-10-17-04:00

I guess the server was returning the timezone as the suffix.

How can I remove the -04:00 with function above?

Thank you very much

The problem is not in the code that you have shown us. I can’t guess where it is then. — Ole V.V., Feb 04 '21 at 17:50
I recommend you don’t use `Calendar`. That class is poorly designed and long outdated. Instead use `LocalDate` from [java.time, the modern Java date and time API](https://docs.oracle.com/javase/tutorial/datetime/). Extra plus: its `toString` method gives you the string that you want. — Ole V.V., Feb 04 '21 at 18:53
@OleV.V. yes, you're right. But the Calendar is generated by jaxb, so I could not decide which will be used. — Hung Bang Quan, Feb 05 '21 at 01:37
I just saw a new thing, thought it can be the root cause of this problem. There are 2 classes same name and package inside jar. they come from 2 different dependencies. The spring boot has picked the first one that is found to use. someway somehow it picked the class that not containing the method above. — Hung Bang Quan, Feb 05 '21 at 01:41
An interesting observation and a likely cause for the behaviour that you have observed, — Ole V.V., Feb 05 '21 at 03:57

I want to confirm that the implementation above is correct. The reason for my problem comes from another aspect. Jaxb has generated 2 classes same name and package inside Jar, and the context will pick the first one that is found to use. As always it was not picking my implementation.
