This makes sense since it makes us more usable even on some file
systems.

             // Now process the prefix and suffix.
             if (prefix.length () < 3)
        -      throw new IllegalArgumentException ("Prefix too short: " + 
prefix);
        +      throw new IllegalArgumentException ("Prefix too short: " + 
prefix + "(valid length 3..7)");
        +    if (prefix.length() >= 8)
        +      throw new IllegalArgumentException("Prefix too long: " + prefix 
+ "(valid length 3..7)");

But is this really necessary on "normal" systems?
My java class libraries book says that the prefix and suffix may be
shortened to produce a valid filename on the underlying system.
But this actually prevents using a long (descriptive) prefix even on
systems that allow them. Is there documentation or behavior with other
systems that mandate this? If not then I think you should revert this
part and find a way to properly truncate the prefix on systems that need
it.

Thanks,
