24 * Color enumeration which demonstrates how to break the enum system.
25 * <p>
26 * The class loader sees the two classes here as independent - the enum
27 * class is nested, not an inner class. Calling getEnumList() on ColorEnum
28 * will return an empty list, unless and until the NestBroken class is
29 * referenced.
