[jira] [Updated] (IGNITE-1744) Serialization problems in case of
cluster with different JDKs vendors and different classes implementations.
[ https://issues.apache.org/jira/browse/IGNITE-1744?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andrey Gura updated IGNITE-1744:
--------------------------------
Description:
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.
Solution discussion started here: https://issues.apache.org/jira/browse/IGNITE-1526?focusedCommentId=14955424&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14955424
