'assertEquals()' may be 'assertSame()'

Reports JUnit assertEquals() calls that can be replaced with an equivalent assertSame() call. This is possible when the arguments are instances of a final class that does not override the Object.equals() method and makes it explicit that the object identity is compared.

Suggests replacing assertEquals() with assertSame().

Example:

@Test
public void testObjectType() {
  Object o = getObject();
  Assert.assertEquals(String.class, o.getClass());
}

After the quick fix is applied:

@Test
public void testSort() {
  Object o = getObject();
  Assert.assertSame(String.class, o.getClass());
}
