JMX monitoring page is not accessible in JIRA 7.10.1

Recently upgraded from JIRA 7.3.4 to 7.10.1. 

The JMX monitoring page located at 

https://<Jira_url>/secure/admin/JmxMonitoringAction.jspa returns 404 page.

I got the answer. I had customized the file atlassian-jira/WEB-INF/classes/actions.xml. Once merged the new changes from Jira 7.10.1, it worked.

This is what I see in logs:

WebworkConfigurationNotFoundException{class=class webwork.config.XMLActionConfiguration, message='No such view mapping', name='JmxMonitoringAction.actionRoles.actionRoles'}
