Checking whether two Lists are the same in JUnit

In this class I'm trying to tests whether i get a correct result from the interiorPoints class. The interiorPoints class is a method that returns a lists of coordinates that lie within a polygon.

Below I'm checking whether the expected result is the same as the actual result which in this case they should be but the test seems to fail for a reason i can't figure out. Can someone help please.

public class TestInteriorPoints {
        private InteriorPoints interiorPoints;
        List<Point> TestPoints;
        List<Point> convexHull;


        /**
         * @throws java.lang.Exception
         */
        @Before
        public void setUp() throws Exception {
            interiorPoints = new InteriorPoints();

            TestPoints = new ArrayList<Point>();
            TestPoints.add(new Point(300,200));
            TestPoints.add(new Point(600,500));
            TestPoints.add(new Point(100,100));
            TestPoints.add(new Point(200,200));
            TestPoints.add(new Point(100,500));
            TestPoints.add(new Point(600,100));

            convexHull = new ArrayList<Point>();
            convexHull.add(new Point(100,100));
            convexHull.add(new Point(100,500));
            convexHull.add(new Point(600,500));
            convexHull.add(new Point(600,100));

        }

        @Test
        public void testInteriorPoints() {
            List<Point> expectedResult = new ArrayList<Point>();
            expectedResult.add(new Point(300,200));
            expectedResult.add(new Point(200,200));

            List<Point> actualResult = new ArrayList<Point>();
            actualResult = interiorPoints.interiorPoints(convexHull, TestPoints);

            assertEquals("TEST5: Check for interior points", expectedResult, actualResult);
            //assertTrue(expectedResult.containsAll(actualResult) && actualResult.containsAll(expectedResult));
        }

    }
