JDK timezone issue on Turkey ("Asia/Istanbul" or "Europe/Istanbul")

Can anyone help with the following problem?

1. My operating system is latest windows 10 and its time zone is (UTC+0300) Istanbul (Daylight saving has been removed and time zone was set to +0300 after the last regulations in Turkey - 7 September 2016)

2. I am using latest JDK which is 1.8.0_131. Tzdata version of this JDK is tzdata2017a which includes time zone changes for Turkey.

This is tiny part of my application that I implemented in main method:

import java.util.Date;
import java.util.TimeZone;

public class TestMain {
  
    public static void main(String[] args) {
        String timeZoneStr = "Asia/Istanbul";
        TimeZone timeZone = TimeZone.getTimeZone(timeZoneStr);
        Date localDate = new Date();
        System.out.println(localDate);
        localDate.setTime(155631515L);
        System.out.println(localDate);
        System.out.println(getUTCFromLocal(localDate, timeZone));
   }

    public static Date getUTCFromLocal(Date localDate, TimeZone localTimeZone) {
         return new Date(localDate.getTime()-localTimeZone.getOffset(localDate.getTime()));
    }
}

Result of the code is :

Sun May 21 15:19:48 EET 2017

Fri Jan 02 21:13:51 EET 1970

Fri Jan 02 19:13:51 EET 1970

According to latest time zone update, last line of output should be "Fri Jan 02 18:13:51 EET 1970", not "Fri Jan 02 19:13:51 EET 1970".

In additon to this, when I create new date object (new java.util.Date()), the information in that object seems correct and time zone on +0300, but if I use setTime method of Date object time zone information changes to +0200.

When date object created with new java.util.Date():

When localDate.setTime(155631515L) method executed:

I also reproduced same issue on other JDK versions.
