Failing test: testTailMapClearThrough

[jobtg]

This is the code being executed:

public void testTailMapClearThrough() {
    final SortedMap<K, V> map;
    try {
      map = makePopulatedMap();
    } catch (UnsupportedOperationException e) {
      return;
    }
    int oldSize = map.size();
    if (map.size() < 2 || !supportsClear) {
      return;
    }
    Iterator<Entry<K, V>> iterator = map.entrySet().iterator();
    Entry<K, V> firstEntry = iterator.next();
    Entry<K, V> secondEntry = iterator.next();
    K key = secondEntry.getKey();
    SortedMap<K, V> subMap = map.tailMap(key);
    int subMapSize = subMap.size();
    subMap.clear();
    assertEquals(map.size(), oldSize - subMapSize);
    assertTrue(subMap.isEmpty());
  }

Problem is we don't override the clear method in the sortedmap, causing it to clear the whole map even if only a submap should be cleared.
