Re: [hibernate-dev] Should LiteralExpression support Enum?
HHH-13016 looks like a duplicate of HHH-12184. Both mention that this
worked in 5.1.10.
The spec is clear that, for queries, this is supported. The overview for
Criteria API states, "The semantics of criteria queries are designed to
reflect those of Java Persistence query language queries."
IMO, this should be supported for Critera queries as well.

Hi,
We had an interesting test case posted this week-end, namely
https://github.com/hibernate/hibernate-orm/pull/2562/files .
Apparently, enums as result of case expressions were (sort of) supported in
5.1, whereas they are not anymore in 5.3: you end up with a NPE.
The issue is that we don't have a ValueHandler for enums and thus the
handler in
https://github.com/hibernate/hibernate-orm/blob/master/hibernate-core/src...
is null.
Not sure if it's something we should support tbh. I mean you can use the
name of the enum instead and I think it would be good enough.
But even if we decide to not support it, I think we should probably provide
a better error than a NPE.
Thoughts?
