For vt-dictionary, you'll have to revert the use of TreeMap#floorKey()
in FileWordList.
See: http://code.google.com/p/vt-middleware/source/diff?spec=svn1690&r=1690&format=side&path=/vt-dictionary/trunk/src/main/java/edu/vt/middleware/dictionary/FileWordList.java
For vt-password, you'll have to remove the @Override annotations from
methods overriding an interface.
There may also be a retroweaver-like tool available for converting 1.6
binaries for use with 1.5, but I'm not aware of one.
