I disagree, use getCause(). Users should see the class as similar to the JDK
as much as possible.
See

http://cvs.apache.org/viewcvs.cgi/jakarta-commons/collections/src/java/org/a
pache/commons/collections/FunctorException.java?rev=1.6&view=auto
Looks good.  I will go ahead and commit something like the simple version 
below, with the improvements in FunctorException.

For those keeping score, this change will make us runtime dependency free :-)

Is using the same name as Throwable for getCause() wise?
Won't this lead to times when you can compile on 1.3, and the code won't
run on 1.4? (unsure, but it seems likely to me).
I'd suggest getThrowable as with Lang. You know it's supported by the
reflection Utils in Lang if someone puts them together, and it keeps
things standard.
