[rules-users] Problem with shadow facts in trunk

[Dirk Bergstrom]

I'm using trunk (revision 10170), and I'm getting an error while asserting
objects.  It looks to be reproducible, in that it only happens with particular
instances of one class.  But since it's in a method of a generated class (the
shadow proxy), I don't have a clue how to debug it.  I had a look at the
buildHashCode method in ShadowProxyFactory, but the magic was too thick for me.
 If it helps, the class being shadowed has boolean, float and long attributes,
but no char, short, int, double or list.

Here's the stacktrace:
