Blocker Description
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.
