             Summary: Bug in creating EnumSet in SimpleAuthorizer example
                 Key: CASSANDRA-5072
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5072
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: John Sanda
            Priority: Minor


In SimpleAuthorizer around line 47 we have,

EnumSet<Permission> authorized = EnumSet.copyOf(Permission.NONE);

This results in an IllegalArgumentException since Permission.NONE is an empty 
set. I think it should be changed to,

EnumSet<Permission> authorized = EnumSet.noneOf(Permission.class);
