Leonardo Uribe commented on MYFACES-2840:
-----------------------------------------

Finally I added a class called AbstractThreadSafeAttributeMap and this one is implemented only for ApplicationMap and SessionMap.

> We can use a copied version of the Enumeration from getAttributeNames() here, because directly using it might cause a ConcurrentModificationException  when performing remove(). Note that we can do this since the Enumeration from getAttributeNames() will contain exactly the attribute names from the time getAttributeNames() was called and it will not be updated if attributes are removed or added.
