Fred edited comment on IGNITE-3429 at 2/13/17 12:49 PM: -------------------------------------------------------- By chance, does anyone have some examples / tests? Upgraded to apache ignite 1.8. I configured BinaryTypeConfiguration with (org.hibernate.cache.internal.OldCacheKeyImplementation) from above then used files from https://issues.apache.org/jira/browse/IGNITE-1794 since on Hibernate 5.2.7. I noticed the BinaryAbstractIdentityResolver being called and returning true but when I call the same service I noticed the database being hit. Also tried switching to Hibernate 4.3.11 and first workaround from above with same results. XML Configuration from http://apacheignite.gridgain.org/v1.6/docs/hibernate-l2-cache ``` hibernate.cache.use_query_cache=true hibernate.cache.use_second_level_cache=true hibernate.cache.region.factory_class=org.apache.ignite.cache.hibernate.HibernateRegionFactory org.apache.ignite.hibernate.default_access_type=READ_ONLY <bean parent="transactional-cache"> <property name="name" value="com.model.Access" /> </bean> @Entity(name = "Person") @Cache(usage = CacheConcurrencyStrategy.READ_WRITE) public class Person ``` was (Author: fwvista): By chance, does anyone have some examples / tests?

This class contains {{type}} field and custom > {{equals}} logic where the type is used as a helper and does not participate > in comparison. Instances of the same type are producing different hash codes > in different JVMs, which actually breaks comparison when binary format is > used, where byte arrays are compared. > The issue is described in more detail here: > http://stackoverflow.com/questions/38132263/apache-ignite-as-hibernate-l2-cache-storing-duplicate-entities -- This message was sent by Atlassian JIRA (v6.3.15#6346)
