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

             Summary: Serialization problems in case of cluster with different 
JDKs vendors and different classes implementations.
                 Key: IGNITE-1744
                 URL: https://issues.apache.org/jira/browse/IGNITE-1744
             Project: Ignite
          Issue Type: Bug
            Reporter: Andrey Gura
            Assignee: Andrey Gura


For example {{BigInteger}} class has different implementations in Orcale and 
IBM JDKs. Serialization of {{BigInteger}} instances works correctly in case of 
{{JdkMarshaller}}, but fails in case of {{OptimizedMarshaller}} or 
{{PortableMarshaller}} because {{getDeclaredFields}} returns different sets of 
fields for Oracle and IBM, so {{OptimizedMarshaller}} calculates checksums that 
are not equal for different vendors. {{PortableMarshaller}} use 
{{OptimizedMarshaller}} for classes with overrided 
{{readObject}}/{{writeObject}}, so it works incorrectly also.
