-------------------------------------------

             Summary: org.hibernate.cache.spi.CacheKey not properly serialized by binary marshaller
                 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
             Fix For: 1.7


{{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
