> CachingPipeline.setup(OutputStream) calls itself resulting in a StackOverflowError [1].
I suppose that it should create a CachingOutputStream first and then call super.setup like
setup(OutputStream outputStream, Map<String, Object> parameters) does [2]. [3] is a
short code fragment to reproduce.

> [2]
> @Override

>      // create a caching output stream to intercept the result
>      this.cachingOutputStream = new CachingOutputStream(outputStream);
>      super.setup(this.cachingOutputStream, parameters);
> }
> [3]
> Pipeline pipeline = new CachingPipeline();
> pipeline.addComponent(new StringGenerator("<x></x>"));
> pipeline.addComponent(new XMLSerializer());
> ByteArrayOutputStream baos = new ByteArrayOutputStream();
> pipeline.setup(baos);
> pipeline.execute();
