Nate Clark commented on HHH-3799:
---------------------------------

Shawn, thanks for the example code. Briefly, if you have a problem calling save()/saveOrUpdate() before adding your objects, then maybe you should be managing the keys instead of letting Hibernate manage them. I'd be happy to continue this discussion off-JIRA, as this is a bit off topic. Please respond directly to my email.

> when persistent set is loaded eagerly in some situations it calls hashcode on its items before their field values are populated and then uses this incorrect hashcode to store them in the set. this makes set items inaccessible by any collection items that rely on hashcode such as contains(), remove(), etc.
> attached is a simple maven test project that reproduces the error, unzip and mvn test to run the test.
