Couldn’t reproduce this anymore on ORM 6+:

We too are seeing this (using Wildfly with Hibernate 5.3.1Final). Anyone have any workarounds for this? It appears this error is being thrown on any objects labeled with @Basic(fetch=FetchType.LAZY) and the object is being updated (saves appear to be working fine though).

Greatly appreciated!

i’m seeing this in 5.4.18 i would love to see this fixed 🙂

Any news? Meet the same issue.

I'm also seeing this issue with OneToOne and NO_PROXY. The issue goes away when I disable the second level cache.
