Wow, proxies as keys in a hashtable... Of course, it's possible to do so but are
you sure you really need this? This leads to high complexity and maybe
poor performance. Anyway, a hashCode() implementation that calls another
database object is not a good idea in any case. I don't see a way around this
"limitation". Can you explain why this is needed in your app? An object that
relies on another object in its hasCode() method should maybe include this
object...
