I've got a concurrency pb :

For info, e is an entreprise object with a set of contact;

Code:

for (Iterator itF = e.getContacts().iterator(); itF.hasNext();) {
   Contact c = (Contact) itF.next();
   if (c.getId()>4){
        e.getContacts().remove(c);
   }
}

What is the better way do delete elts of an existing Set ?

Code:

for (Iterator itF = new ArrayList(e.getContacts()).iterator(); itF .hasNext();) 
?

Thanks,

Fabien.

Now before someone jumps in and says this isn't really a hibernate question but a plain old Java one, I'll give the answer ;)

Just call itF.remove() instead of e.getContacts().remove(c) and the ConcurrentModificationException will go away.
