> Looking at the code it is noted that the cache is backed by a HashSet. 
> Would it be possible to change this so that it is backed by a LinkedHashSet.
> There may or may not be performance benefits to this dependant on the usage. The primary reason for wanting it to be backed by a LinkedHashSet is the guaranteed ordering of the elements when iterated over. Having this guarantee would facilitate implementations of say a TableModel, but would make other iterations more predictable too.
