      public class NestedIOException
      extends IOException

  Subclass of `IOException` that properly handles a root cause, exposing the root cause just like NestedChecked/RuntimeException does.

  Proper root cause handling has not been added to standard IOException before Java 6, which is why we need to do it ourselves for Java 5 compatibility purposes.

  The similarity between this class and the NestedChecked/RuntimeException class is unavoidable, as this class needs to derive from IOException.
