I see errors in the log such as:
2016-12-12 15:17:19,554 http-nio-8073-exec-5 uri:/secure/AjaxIssueAction!default.jspa username:BLAH ERROR BLAH 917x18093x1 uxk15a 10.109.12.175 /secure/AjaxIssueAction!default.jspa [c.a.j.plugin.issuetabpanel.IssueTabPanelInvokerImpl] showPanel does not implement IssueTabPanel.com.atlassian.jira.plugin.issuetabpanel.IssueTabPanel3Adaptor(com.atlassian.jira.issues.Issue, com.atlassian.crowd.embedded.api.User). This likely means the plugin is not compatible with this version of JIRA.
I searched and found the resolution was to disable the plugin, but I would like to keep the functionality without all the errors in the logs. Any ideas?
