The Apache Commons Bidirectional Map [1] is the best data structure for bug 58740. I have found so far that will encapsulate the complexity of needing to look up by index or value while keeping good performance. It looks like Apache Commons Collections is not currently a pre-requisite for building POI [3]. Is this something worth adding as a dependency to POI, or should I duplicate the BiDiMap implementation into an internal POI class?
