I'm getting the following exception when I try to get the size of a HashSet.

I can run a <jx:forEach> on the HashSet and it works fine, but when I
try and get the size I get an error.  Here's what I'm doing to get the
error:  ${item.getAttributes().size()}
item.getAttributes() returns a HashSet with 2 items in it.
This is due to how Jexl treats size function. size is a keyword in jexl 
that can be applied only to types known to jexl itself. Among these:
- ArrayList
- List
and some other. the problem is that there is no java.util.Set there. The 
patch is a 2-liner. Had no time to send a patch though.
