duplicated code

[Tom Tromey]

A fellow Red Hatter, Vadim Nasardinov, has a program that looks for
cut-and-paste code.  He ran it on Classpath, you can see the results
here:

The program itself is here:

http://pmd.sourceforge.net

I looked through the results briefly... some of it is unavoidable
(either machine generated code like the Locale stuff or multiple
copies of code in Arrays).  However, at least the character set tables
could be shared between the input and output classes.
