[jira] [Created] (KNOX-2297) NPE during cleanup?
Kevin Risden created KNOX-2297:
----------------------------------
Summary: NPE during cleanup?
Key: KNOX-2297
URL: https://issues.apache.org/jira/browse/KNOX-2297
Project: Apache Knox
Issue Type: Bug
Components: Server
Reporter: Kevin Risden
Assignee: Kevin Risden
Fix For: 1.4.0
I saw this while hitting Knox repeatedly during topology redeploys/restarts. There should never be a NPE.
