Re: orm.xml mappings do not support mapping the same entity class twice (
https://hibernate.atlassian.net/browse/HHH-15698?atlOrigin=eyJpIjoiYTk3OT...
)
OK, so there doesn’t seem to be any very straightforward way out of this, either:
* we un-deprecate hbm.xml , since it's the only way to specify an explicit entity
name,
* introduce a brand new XML mapping format, derived from orm.xml , but with the ability to
specify entity names for entities and associations, or
* we deprecate the remaining methods of Session that accept a string entityName , since
they’re only useful with the deprecated hbm.xml mapping format.
Note that it would not help to introduce new annotations, since you can’t define multiple
mappings for a single class in annotations. (Nor you can you define mappings for
{{Map}}s.)
So what we’re contemplating here is losing:
* the ability to map a class multiple times with different entity names, and
* the ability to persist a Map.
