2017-10-29 10:09:19,123 http-nio-8750-exec-25 WARN admin 609x5002x1 1x9am3h xx.xx.xx.xx /secure/ShowAttachScreenshotFormAction.jspa [c.a.j.w.a.issue.util.BackwardCompatibleTemporaryAttachmentUtil] Using deprecated method for adding attachments to issue! Someone still uses TemporaryAttachmentsMonitor - you can probably track him by looking at the referrer or previous requests to JIRA.

Workaround - Temporary

This is useful when you want to see if the problem is resolved, or can't afford an application restart:

• Go to Jira Admin > Logging and Profiling
• Click "Configure logging level for another package"
• Add each class name shown below, with the level set to ERROR

  com.atlassian.jira.web.action.issue.util.BackwardCompatibleTemporaryAttachmentUtil
  com.atlassian.jira.issue.managers.DefaultAttachmentManager
  com.atlassian.jira.issue.fields.AttachmentSystemField
  

Workaround - Permanent

You can add the following to $jira-install/atlassian-jira/WEB-INF/classes/log4j.properties - and restart Jira.
