Subject [jira] [Commented] (IGNITE-3429) org.hibernate.cache.spi.CacheKey not properly serialized by binary marshaller
Date Tue, 18 Apr 2017 20:13:41 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-3429?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15973399#comment-15973399

Denis Magda commented on IGNITE-3429:
-------------------------------------

Binary resolvers based workaround is no longer applicable for 2.0. The issue has to be fixed
differently. See the discussion:

> {{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.
