Is this a bug in Java.Calendar in Linux? Year not updated

I've got something strange happening in a server running Linux, while a windows machine performing the same code behaves normally.

It is happening with the following code:

    public static final SimpleDateFormat sqlDateFormat = new SimpleDateFormat("Y-M-d");

    Calendar cal = Calendar.getInstance();
    String now = sqlDateFormat.format(cal.getTime());
    System.out.println(now);
    cal.add(Calendar.DAY_OF_MONTH, -4);
    cal.set(Calendar.HOUR_OF_DAY, 0);
    cal.set(Calendar.MINUTE, 0);
    String trsh = sqlDateFormat.format(cal.getTime());
    System.out.println(trsh);

The output on the windows machine running:

    java version "1.7.0_07"
    Java(TM) SE Runtime Environment (build 1.7.0_07-b11)
    Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)

    Output:
    2014-01-02
    2013-12-29

The above is matching the expected result.

The output on the Linux machine running:

    java version "1.8.0-ea"
    Java(TM) SE Runtime Environment (build 1.8.0-ea-b108)
    Java HotSpot(TM) 64-Bit Server VM (build 25.0-b50, mixed mode)

    Output:
    2014-01-02
    2014-12-29

This is odd isn't it? Any nice workarounds?
