It looks like I'm running into the problem inside EntityCodex.decode() :
In the red code below, I see it iterate over all three items in my
collection, but each time the "element" that comes out of the "decode" call
has the same hashCode, so the HashSet ignores it. The hashCode always seems
to be "1832980284", regardless of what the actual hashCode of my underlying
object is.
Does anyone know if it is possible to control this behavior? I guess worst
case I could change my Set to a List and just remove any duplicates myself,
but it seems weird to have Set support if it doesn't work right.
Thanks,
Eric
