I stopped using emacs for my Java/Groovy code ever since IntellijIDEA came
around, so can't give you an expert advice. IDEA has an option to remove the
trailing spaces only for modified lines. This way you will avoid messing up
anything you haven't touched.
You also can do
git diff --check
to see if any whitespace changes were introduced.
