Steps to reproduce:
1. This happens intermittently when a capture starts. Sometimes it would show up as "FAILED", before changing to their correct "CAPTURING" state.
Per http://opencast.3480289.n2.nabble.com/JIRA-Ticket-Cleanup-proposal-td7475080.html, this has been bulk resolved as won't fix. If this is still important to you please reopen and we can triage as appropriate.
