---------------------------------

             Summary: Setting topology.groups to nil could break 
SimpleACLAuthorizer
                 Key: STORM-565
                 URL: https://issues.apache.org/jira/browse/STORM-565
             Project: Apache Storm
          Issue Type: Bug
    Affects Versions: 0.9.3-rc2
            Reporter: Derek Dagit
            Priority: Minor


https://github.com/apache/storm/blob/f8bce2225f2cfc550dcc67dff469f87062686506/storm-core/src/jvm/backtype/storm/security/auth/authorizer/SimpleACLAuthorizer.java#L114

If a user would happen to include this config, but set its value to nil, then 
we could see an NPE here.
