    - #### onUnparseableExtraField

          ZipExtraField onUnparseableExtraField(byte[] data,
                                                int off,
                                                int len,
                                                boolean local,
                                                int claimedLength)
                                         throws ZipException

      Decides what to do with extra field data that doesn't follow the recommended pattern.
      Parameters:
        `data` - the array of extra field data
        `off` - offset into data where the unparseable data starts
        `len` - the length of unparseable data
        `local` - whether the extra field data stems from the local file header. If this is false then the data is part if the central directory header extra data.
        `claimedLength` - length of the extra field claimed by the third and forth byte if it did follow the recommended pattern
      Returns:

      Throws:
        `ZipException` - if an error occurs or unparseable extra fields must not be accepted
