Hi,
Here are two small cleanup patches.
First one replaces all Vector references with List (usage) and ArrayList (creation).
Second replaces all Hashtable references with Map (usage) and HashMap (creation).
Reasons:
* Theoretically faster since the ArrayList/HashMap are not synchronized
* Using interfaces makes changing of List/Map implementations easier at later time
* Vector/Hashtable were deprecated already in Java 1.2
