Description

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.

[1]
@Override
public void setup(OutputStream outputStream) {
    this.setup(outputStream);
}

[2]
@Override
public void setup(OutputStream outputStream, Map<String, Object> parameters) {
     // 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();
