Magento Java Soap Gzip Compression
===

I tried to compress the communication channel between a soap client and magento :

public static MageApiModelServerWsiHandlerPortType getInstance() {
		
		Client client = null;
		
		if (instance == null) {
			try {
				logger = Logger.getLogger(SoapClient.class);
				Properties properties = Property.getInstance(PropertyType.Application);
				String url = properties.getProperty("magUrl");
				
				if (url != null) {
					//logger.info("Creating service...");
					MagentoService service = new MagentoService(new URL(url));
					//logger.info("Calling port...");
			    	instance = service.getMageApiModelServerWsiHandlerPort();
			    	
			    	client = ClientProxy.getClient(instance);
		    		
		    		HTTPConduit http = (HTTPConduit) client.getConduit();
		    		HTTPClientPolicy httpClientPolicy = new HTTPClientPolicy();
		    		httpClientPolicy.setAllowChunking(false);
		    		httpClientPolicy.setConnectionTimeout(36000);
		    		
		    		http.setClient(httpClientPolicy);
		    		
		    		client.getInInterceptors().add(new GZIPInInterceptor());
			    	client.getOutInterceptors().add(new GZIPOutInterceptor());
		    ...

which works fine for calling various types of data. But when it comes to creating a product, the sender (magento) returns following error:
