I agree that the commens-collections solution is preferable as JDK 1.3 is still "supported" AFAIK.
There seems to be a consensus to utilize commons-collections, so I will comply, as it really doesn't matter for me. But what is meant by JDK 1.4's Linked stuff? If you refer to LinkedList, that's even present in JDK 1.2.
JDK 1.4 has a LinkedHashMap that allows you to pull keys in insertion order. Unfortunately it doesn't really apply here, as the SWCL is using the depracated Dictionary/Enumeration approach instead of Collection's Map/Iterator one. I would suggest to leave that untouched for now, but most probably some refactoring could be helpful in the near future.
