             Summary: Improper JavaDoc comment for FilenameUtils.indexOfExtension
                 Key: IO-436
                 URL: https://issues.apache.org/jira/browse/IO-436
             Project: Commons IO
          Issue Type: Bug
          Components: Utilities
    Affects Versions: 2.4
            Reporter: Christoph Schneegans
            Priority: Trivial


The method FilenameUtils.indexOfExtension contains this JavaDoc comment:

  * @param filename  the filename to find the last path separator in, null returns -1
  * @return the index of the last separator character, or -1 if there
  * is no such character

This comment was obviously copied from the FilenameUtils.indexOfLastSeparator method, where it makes perfect sense.

The JavaDoc comment for FilenameUtils.indexOfExtension should rather read e.g. as follows:

  * @param filename  the filename to find the last extension separator in, null returns -1
  * @return the index of the last extension separator character, or -1 if there
  * is no such character
