Hello, I am encountering this exception on an intermittent basis and could not figure why its so infrequent. It seems this happens on Session.load() and not able to query the object. I read a few forums on this on changing the primary key's datatype, but not convinced is thats the core issue. If any of you have encountered this, kindly help.
