* Provides a convenient extension of the {@link ServletInputStream} class that can be subclassed by developers wishing
* to adapt the behavior of a Stream. One such example may be to override {@link #close()} to instead be a no-op as in
* SOLR-8933.
*
* This class implements the Wrapper or Decorator pattern. Methods default to calling through to the wrapped stream.
