That would have been a great solution, but unfortunately it doesn't
work. *sigh*

Nope, I tried creating a dummy class that simply had a static method in
it to return a null, but when I try to pass that value CF says that the
var doesn't exist:
<cfscript>
nullobj = createObject("java", "NullTest");
nullstr = nullobj.getNull();
out = nullobj.testNull(nullstr);
</cfscript>
The above throws an error saying that nullstr doesn't exist: verified by
isdefined("nullstr") returning FALSE. BTW, that's contrary to the CF
docs that say a NULL value returned from a Java method is converted to
an empty string ("") when it's used...

First I tried extending the original class and overriding the method
name with a new signature which only took the correct params in and used
a super.* call to the extended class's real function, but there were all
sorts of problems in casting the original instance into an instance of
my class, so I gave up on that one.
In the end I went with the idea of creating a separate "interface" class
(not actually a Java interface) which I can call from CF with the
correct params and have that deal with the main chuck of the work.
Surely someone could have found a nice simple way of using a null
value!? Or did that one pass by the bobs at Macromedia...? ;o)
