Summary: ClassCastException from SortedSet
Initial Comment:
I've attached details from a forum message, along with
a stack trace below
<snip source="forum">
I'm not sure if this is related, but we are getting a
ClassCastException because TreeMap is trying to cast
our objects into Comparables since it can't find a
Comparator. We defined a comparator, though, and it
looks like it's copied most of the time.
However, it looks like this constructor for SortedSet:
public SortedSet(SessionImplementor session,
java.util.SortedSet set) {
super(session, set);
}
..should copy the comparator as well. When this
constructor is called by SortedSetType.wrap(...), the
comparator isn't copied to the hibernate SortedSet
class from the java.util.SortedSet class.
Is this behavior intentional, or is this a bug?
