Description

add() method of listIterator implementation in AbstractList may throw unexpected ConcurrentModificationException.
Its behavior is different from the one of RI.

Here is the test case:

public class AbstractListTest extends junit.framework.TestCase {

public void test_listIterator()

{ list = new MockArrayList(); ListIterator it = list.listIterator(); it.add("one"); it.add("two"); assertEquals(2,list.size()); }

class MockArrayList<E> extends AbstractList<E> {

ArrayList<E> list = new ArrayList<E>();

public E remove(int idx)

{ modCount++; return list.remove(idx); }

@Override
public E get(int index)

{ return list.get(index); }

@Override
public int size()

{ return list.size(); }

@Override
public void add(int idx, E o)

{ modCount += 10; list.add(idx, o); }

}

}

Test results:
RI can pass this test.
Harmony will throw a ConcurrentModificationException.
