[jira] [Commented] (JCR-3426) Log warning when changes are performed with event notification thread

["Bart van der Schans (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JCR-3426?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13457112#comment-13457112 ] 

Bart van der Schans commented on JCR-3426:
------------------------------------------

If there are valid (exceptional) use cases for using the notification thread to make changes, then logging the full stack trace on WARN might be a bit too verbose. In that case we might consider logging the full stack only on debug level with a reference to it in the warning with something like: "full stack trace available on debug"
