Looks really nice. Finally some numbers on FOPs performance, the tests
you did seem to make sense. Thank you for this work! I think this should
be merged as soon as possible.

I've just committed the following changes:
- Fixed PMD to report only basic issues and important security issues.
run "ant pmd" to get this report. This is something I'll look into
changing in fop trunk after the merge.
- added the PMD/CPD (Copy'n'paste detection) report, run "ant cpd" to
generate it. Anything reported here should definitely be refactored.
Again, I'll look into some of these things after your merge.

PMD requires JDK 1.5 (only needed for report, and not for normal build
or use, hope this is ok)

Hotspot does pretty well on inlining static functions, duplicate code
could therefore go into static functions in utility classes if they
would not make sense in the class hierachy.
