Description

The PortletV3Demo and PortletHubDemo projects both have an image selector portlet that relies on the following data structure in order to map values in a drop-down list to relative image paths:

Constants.java

public final static Map<String, String> imgMap = new HashMap<String, String>() {
   private static final long serialVersionUID = 1L;
{
   put("baseball", "/resources/images/baseball-trans.gif");
   put("golfball", "/resources/images/golfball-trans.gif");
   put("fussball", "/resources/images/fussball-trans.gif");
}};

This task involves refactoring the structure so as to avoid setting a default serialVersionUID.
