Buggy source:
public void executeGetAllBuckets(HttpServletRequest request,HttpServletResponse response) throws IOException, XMLStreamException {
  Calendar cal=Calendar.getInstance();
  cal.set(1970,1,1);
  S3ListAllMyBucketsRequest engineRequest=new S3ListAllMyBucketsRequest();
  engineRequest.setAccessKey(UserContext.current().getAccessKey());
  engineRequest.setRequestTimestamp(cal);
  engineRequest.setSignature("String_Node_Str");
  S3ListAllMyBucketsResponse engineResponse=ServiceProvider.getInstance().getS3Engine().handleRequest(engineRequest);
  ListAllMyBucketsResponse allBuckets=S3SerializableServiceImplementation.toListAllMyBucketsResponse(engineResponse);
  OutputStream outputStream=response.getOutputStream();
  response.setStatus(200);
  response.setContentType("String_Node_Str");
  StringBuffer xml=new StringBuffer();
  xml.append("String_Node_Str");
  xml.append("String_Node_Str");
  xml.append("String_Node_Str");
  xml.append(engineResponse.getOwner().getID()).append("String_Node_Str");
  xml.append("String_Node_Str").append(engineResponse.getOwner().getDisplayName()).append("String_Node_Str");
  xml.append("String_Node_Str").append("String_Node_Str");

    xml.append("String_Node_Str").append(sdf.format(entry.getCreationDate().getTime())).append("String_Node_Str");
    xml.append("String_Node_Str");
  }
  xml.append("String_Node_Str").append("String_Node_Str");
  response.setStatus(200);
  response.setContentType("String_Node_Str");
  S3RestServlet.endResponse(response,xml.toString());
}

Fixed version (ground truth):
public void executeGetAllBuckets(HttpServletRequest request,HttpServletResponse response) throws IOException, XMLStreamException {
  Calendar cal=Calendar.getInstance();
  cal.set(1970,1,1);
  S3ListAllMyBucketsRequest engineRequest=new S3ListAllMyBucketsRequest();
  engineRequest.setAccessKey(UserContext.current().getAccessKey());
  engineRequest.setRequestTimestamp(cal);
  engineRequest.setSignature("String_Node_Str");
  S3ListAllMyBucketsResponse engineResponse=ServiceProvider.getInstance().getS3Engine().handleRequest(engineRequest);
  S3SerializableServiceImplementation.toListAllMyBucketsResponse(engineResponse);
  response.getOutputStream();
  response.setStatus(200);
  response.setContentType("String_Node_Str");
  StringBuffer xml=new StringBuffer();
  xml.append("String_Node_Str");
  xml.append("String_Node_Str");
  xml.append("String_Node_Str");
  xml.append(engineResponse.getOwner().getID()).append("String_Node_Str");
  xml.append("String_Node_Str").append(engineResponse.getOwner().getDisplayName()).append("String_Node_Str");
  xml.append("String_Node_Str").append("String_Node_Str");
  SimpleDateFormat sdf=new SimpleDateFormat("String_Node_Str");
  for (  S3ListAllMyBucketsEntry entry : engineResponse.getBuckets()) {
    xml.append("String_Node_Str").append("String_Node_Str").append(entry.getName()).append("String_Node_Str");
    xml.append("String_Node_Str").append(sdf.format(entry.getCreationDate().getTime())).append("String_Node_Str");
    xml.append("String_Node_Str");
  }
  xml.append("String_Node_Str").append("String_Node_Str");
  response.setStatus(200);
  response.setContentType("String_Node_Str");
