Query cache key generated for HQL with a "joined" association is the same as when the association is "fetched", even though results are different ------------------------------------------------------------------------------------------------------------------------------------------------- Key: HHH-5630 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5630 Project: Hibernate Core Issue Type: Bug Components: query-hql Affects Versions: 3.6.0.CR2 Reporter: Gail Badner Assignee: Gail Badner Fix For: 3.6.x The same SQL is generated for the following HQL statements: 1) select a from Animal a left join fetch a.offspring 2) select a, o from Animal a left join a.offspring o The QueryKey objects generated for these statements are equivalent, even though the cached data is different. Results from 1) will be a list of Animal objects. Results from 2) will be a list of Object[2] This can cause type mismatches when retrieving results frome the cache.
