ConcurrentModificationException

I have a problem concerning ConcurrentModificationException in a multithreaded program. I

I thought that one getsConcurrentModificationException while iterating over collections.

Therefore I replaced nearly all iterations over Lists by Iterations

over arrays which I obtain with the List#toArray() method.

Some iterations I replaced by numeric loops going from List#size()

down to zero and obtain the list elements with List#get(int).

I expected that the ConcurrentModificationException disappears but it still occasionally comes.

Do you think I overlooked an iterator or is there another explanation?
