--------------------------------------------------------
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
```

Also, getting Caused by: java.lang.NoSuchMethodException:
org.hibernate.cache.internal.OldCacheKeyImplementation.<init>() since
org.hibernate.cache.internal.OldCacheKeyImplementation doesnt have a default
constructor.

> Key: IGNITE-3429
> URL: https://issues.apache.org/jira/browse/IGNITE-3429
> Project: Ignite
> Issue Type: Bug
> Components: cache, Hibernate L2 cache
> Affects Versions: 1.6
> Reporter: Valentin Kulichenko
> Assignee: Andrew Mashenkov
> Priority: Critical
> Fix For: 2.0
>
>
> {{org.hibernate.cache.spi.CacheKey}} is a class used as a key for all entries
> in the Hibernate L2 cache. 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:
