org.hibernate.cache.infinispan.query.QueryResultsRegionImpl not caching queries (marked as setCacheable(true) ), if transaction rollsback. This reproduces only for query cache, region cache works correct. This is not correctness, but performance issue.
Test case:
openSession
beginTransaction
execute any cacheable query
rollback transaction
close session
repeat
config parameters
<property name="hibernate.cache.use_second_level_cache">true</property>
<property name="hibernate.cache.use_query_cache">true</property>
<property name="hibernate.cache.auto_evict_collection_cache">true</property>
<property name="hibernate.cache.region.factory_class">org.hibernate.cache.infinispan.InfinispanRegionFactory</property>
<property name="hibernate.cache.infinispan.cfg">org/hibernate/cache/infinispan/builder/infinispan-configs-local.xml</property>

Possible wokaround:
Instead of rollback execute session.clear than commit. But this may affect perfomance, since databases can optimize rollbacks.
