027 * Exception indicating that a recursive delete can't be performed because the file system does not
028 * have the support necessary to guarantee that it is not vulnerable to race conditions that would
029 * allow it to delete files and directories outside of the directory being deleted (i.e.,
030 * {@link SecureDirectoryStream} is not supported).
031 *
032 * <p>{@link RecursiveDeleteOption#ALLOW_INSECURE} can be used to force the recursive delete method
033 * to proceed anyway.
