So, it doesn’t seem related to the cache engine used. * Disabling 2nd level cache avoids the issue * Disabling batch fetch also avoids the issue Although trying to find EntityB with EntityA id could be considered an application/logic bug by itself, I would expect hibernate to have a consistent behaviour enabling or disabling batch fetch; or enabling or disabling 2nd level cache and do not throw ClassCastException, but rather return null.

The workaround is to write cast(null as String) but that should not be necessary.
