Re: Yet another ConcurrentModificationException question

Apologies for asking about this FAQ. I have looked up the relevant
java tutorial but I just want to check my understanding with the
following example.

Iterator oIterator = m_oCollection.iterator();
while( oIterator.hasNext()) {
           Element oElement = (Element)oIterator.next();
           String sOIDValue =
oElement.getAttribute(oElement.getOIDKey());
           if( sOIDValue != null && sOIDValue.equals(sElementOID) ) {
               // We have a match
               return oElement;
           }
       }

If I know that neither getAttribute() or getOIDKey() can alter the
"structure" of m_oCollection, is it true to say that a
ConcurrentModificationException thrown from within the body of the
while loop above, *must* have been caused by another thread altering
the structure of m_oCollection?

So to prevent this from happening, I can make m_oCollection a
synchronized Vector (currently it is just a normal vector), and put
this while loop inside a synchronized block.

Many Thanks,
Andy
