[jboss-jira] [JBoss JIRA] (WFLY-5836) Stale session data received when using REPL SYNC on jvmkill
[
https://issues.jboss.org/browse/WFLY-5836?page=com.atlassian.jira.plugin....
]
Radoslav Husar closed WFLY-5836.
--------------------------------
Assignee: Radoslav Husar (was: Paul Ferraro)
Resolution: Rejected
This can happen in this scenario, when the server crashes after the client response is
committed but before the transaction was committed. An indication of a problem would have
been "off by 2" versions of the session implying a stale data read.
