"""Runs findbugs, and returns an error code if there are new warnings.
This runs findbugs with an additional flag to exclude known bugs.
To update the list of known bugs, do this:

   findbugs_diff.py --rebaseline

Note that this is separate from findbugs_exclude.xml. The "exclude" file has
false positives that we do not plan to fix. The "known bugs" file has real
bugs that we *do* plan to fix (but haven't done so yet).

Other options
  --only-analyze used to only analyze the class you are interested.
  --relase-build analyze the classes in out/Release directory.
  --findbugs-args used to passin other findbugs's options.

Run
  $CHROM_SRC/third_party/findbugs/bin/findbugs -textui for details.
