[jira] [Commented] (DBCP-424) validateLifetime causes needless
warnings about swallowed exceptions to be logged
[ https://issues.apache.org/jira/browse/DBCP-424?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14083089#comment-14083089 ]
Sebb commented on DBCP-424:
---------------------------
Presumably the idea is that it should not be possible for the max lifetime to be exceeded unless there is a bug in the code.
In this particular case, the excess is quite small, and is presumably caused by a slightly delayed cleanup.
As such, I agree it should not be logged. However, if the excess were much bigger, then it probably would be worth reporting.
Have you seen any larger excess values?

> the validateLifetime method in PoolableConnectionFactory is causing the following warning to be logged, even though it is not an exceptional case. While it is not impairing functionality, we have to work around the issue.
