There's a "spurious" warning from javadoc concerning breakiterator -

it doesn't like a doc comment that starts:

   /**
     * {@inheritDoc}
     *
     * <p>additional text ...
     */

With the -breakiterator option, there is no warning.
Without the -breakiterator option, the warning is:

C.java:8: warning - The first sentence is interpreted to be:
"{@inheritDoc}"
This sentence is different from what will be interpreted as the first sentence
in the next major release (when that interpretation will be internationalized),
which is:
"{@inheritDoc}

 <p>additional text ..."
To avoid this note, change the doc comment to make this a proper first sentence,
then use -breakiterator from that point forward, which will output this new
sentence.
