Subject [jira] [Commented] (IGNITE-11734) IgniteCache.replace(k, v, nv) requires classes when element is null
Date Fri, 19 Jul 2019 08:16:00 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-11734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16888683#comment-16888683
] 

Stanislav Lukyanov commented on IGNITE-11734:
---------------------------------------------

[~v.pyatkov] I came across this issue and the fix, and I believe the test has a flaw. If `replace`
throws an exception other than `ClassNotFoundException` then it will be ignored. Do you agree,
or am I missing something?
