Given:
* A simple entity
* One attribute maps a jdbc VARCHAR to a SortedSet<Integer> using a custom user type
* Another attribute maps the very same VARCHAR column to a normal String field, but having it readonly (updatable=false and insertable=false)
When:
* When querying this entity
Then:
* An exception happens because hibernate mixes both properties java types

The only reason I need to map this column twice is:
* to be able to use it in HQL → {{e.sortedIdsExpression like :expression}}
This works fine in latest Hibernate 5
I’ll attach the test Test case as soon the Jira issue number is created attached and also available in my github repository [https://github . com/ratoaq2/HHH-16250|https://github.com/ratoaq2/HHH-16250|smart-link] |
