[jira] [Commented] (DIRAPI-337) ClosedSelectorException while
searching through LDAP
[ https://issues.apache.org/jira/browse/DIRAPI-337?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17204815#comment-17204815 ]
Natan Abolafya commented on DIRAPI-337:
---------------------------------------
I get this sometimes when I call _LdapConnectionPool.close()._ Couldn't figure out any pattern on that but it's probably what you said. Connection is already closed by the remote server.
But I think the way the library handles this can be improved. The exception occurs on a standalone thread and provides no way to handle it as it's not delegated anywhere. So it ends up on a `DefaultExceptionMonitor`, polluting the logs.
