[luni] Can not set negative value to java.util.GregorianCalendar.ZONE_OFFSET
----------------------------------------------------------------------------

                 Key: HARMONY-2422
                 URL: http://issues.apache.org/jira/browse/HARMONY-2422
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Artem Aliev


If try to set negative value to ZONE_OFFSET field, it will be changed
to some positive value. RI doesn't have such behavior.

Probably compatibility issue.

Test to reproduce:

import junit.framework.TestCase;

import java.util.GregorianCalendar;

public class Test extends TestCase {

        public void testcase() {
                GregorianCalendar gc = new GregorianCalendar(1, 1, 1);
        System.out.println("gc = " + gc);
        gc.set(GregorianCalendar.ZONE_OFFSET, -1);
        System.out.println("gc.get(" + GregorianCalendar.ZONE_OFFSET + ") = " +
gc.get(GregorianCalendar.ZONE_OFFSET));
        assertTrue("gc.get(" + GregorianCalendar.ZONE_OFFSET + ") == -1",
(gc.get(GregorianCalendar.ZONE_OFFSET) == -1));
    }
}
