Creating an object
hash = createObject("java","java.util.Hashtable");
should NOT cause any problems unless your saying hash is a function
name in CF that I have never heard of. However, having hash as a
function name in the util package won't cause any conflicts as there
is nothing wrong with referencing hash.hash(); though it may be odd to
read for some people.
It is actually pretty common to define a new instance of
java.util.Hashtable as hash:
import java.util.*;
...
...
Hashtable hash = new Hashtable(4);
...
...
