Description

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);
