I don’t know if this is a new feature in Java 5 that I did not know before or I just did not know this is possible in Java. But I learned today that you can do static declaration of collection types as below:

public static List supportedCopyPropertyTypes = new ArrayList() {
		private static final long serialVersionUID = 660145948432567403L;
		{
			add("String");
			add("BigDecimal");
			add("int");
		}
	};
