}{code}
when create jpa query, do projection with dto and try to get the verison field, root.get("version"), an exception throwed. i debug into the source code of hibernate, i found final Property declaredVersion = persistentClass.getDeclaredVersion(); getDeclaredVersion is null, but getVersion has value.
exception details:
