The spec of javax.accessibility package can be updated and the next rules can be applied:
 - <tag> should be replaced by {@tag }
 - 80 column limit
 - description of the class/method/field should be followed by dot
 - @param, @return should not end with a dot, except a case when more than one sentences are used
 - empty line after description/before the first tag was added
 - unnecessary empty lines were removed
 - sets of spaces in the middle of text were deleted
 - @param, @throws, @return should be aligned, to be more readable
 - unnecessary imports should be removed
 - the "null"/"true"/"false"/"this" should be wrapped in {@code } when necessary
 - the order of different tags were unified across the package
