[JBoss JIRA] (ISPN-5356) Transactional, optimistic-locked caches do not honour Flag.FAIL_SILENTLY
by Galder Zamarreño (JIRA)
[ https://issues.jboss.org/browse/ISPN-5356?page=com.atlassian.jira.plugin.... ]
Galder Zamarreño commented on ISPN-5356:
----------------------------------------
I've created a fix which should be integrated soon.
However, I do think it's very risky to do what you are doing with query caching. If your queries are updating so often you are getting lock timeouts, query cache might better be disabled, otherwise you're hardly getting any benefits from having it. Using FAIL_SILENTLY and ZERO_LOCK_TIMEOUT with query cache could skip installing query updates correctly, leading to stale query results...
