This is a collection of patches which addresses about 2,150 Checkstyle complaints. Each ZIP file should be unzipped, and be sure to recreate directory structure! You will find a structure that matches the source repo. I created a single patch file for each package within each subproject that has changes, so it should be quite granular enough. Also note that there are some new package.html files in some places which should be added. I will be happy to do another round once these are applied.
