-------------------------------------------------------
I put in a temporary workaround in the time being which sets SessionFactory to
null:
public class SgrOptimizedMarshaller extends OptimizedMarshaller {
@Override
public byte[] marshal(Object obj) throws IgniteCheckedException {
if (obj instanceof CacheKey) {
CacheKey key = (CacheKey) obj;
Class<?> cacheKeyClazz = obj.getClass();
try {
Field typeField =
cacheKeyClazz.getDeclaredField("type");
typeField.setAccessible(true);
Type hibernateType = (Type) typeField.get(key);
if (hibernateType instanceof ComponentType) {
ComponentType componentType =
(ComponentType) hibernateType;
Class<?> componentTypeClazz =
componentType.getClass();
Field componentTypeField =
componentTypeClazz.getDeclaredField("typeScope");
componentTypeField.setAccessible(true);
componentTypeField.set(componentType,
null);
}
} catch (Exception ex) {
System.out.println(ex.toString());
}
}
return super.marshal(obj);
}
}

> Key: IGNITE-3429
> URL: https://issues.apache.org/jira/browse/IGNITE-3429
> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 1.6
> Reporter: Valentin Kulichenko
> Priority: Critical
> Fix For: 1.8
>
>
> {{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:
> http://stackoverflow.com/questions/38132263/apache-ignite-as-hibernate-l2-cache-storing-duplicate-entities
