Error in Italian time format

FULL PRODUCT VERSION :
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Linux kichemaru 3.10.17 #2 SMP Wed Oct 23 16:34:38 CDT 2013 x86_64 Intel(R) Core(TM) i7-5600U CPU @ 2.60GHz GenuineIntel GNU/Linux



A DESCRIPTION OF THE PROBLEM :
The Italian time format seems to be wrong.

We wrote the following class:

import java.text.DateFormat;
import java.util.Locale;
import java.util.Date;
 
public class ItalyTime {
    public static final void main(String[] args) {
        Locale locale = Locale.forLanguageTag("it-IT");
        Date date = new Date();
        DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.MEDIUM, DateFormat.MEDIUM, locale);
        System.out.println(dateFormat.format(date));
    }
}

And got the following output:
28-set-2016 14.46.17

I am Italian and have never seen the hour, minutes and seconds separated by a dot, but always separated by a colon.

Would it be possible to have this fixed please?

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
We wrote the following class:

import java.text.DateFormat;
import java.util.Locale;
import java.util.Date;
 
public class ItalyTime {
    public static final void main(String[] args) {
        Locale locale = Locale.forLanguageTag("it-IT");
        Date date = new Date();
        DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.MEDIUM, DateFormat.MEDIUM, locale);
        System.out.println(dateFormat.format(date));
    }
}

And got the following output:
28-set-2016 14.46.17

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
28-set-2016 14:46:17
ACTUAL -
28-set-2016 14.46.17

REPRODUCIBILITY :
This bug can be reproduced always.
