JDK API for compress byte array

API: int java.util.zip.Deflater.deflateBytes(byte[] b, int off, int len)

Usage Scenarios:
1. decrease communication load
2. decrease cache load for receiver when data amount too large
3. comrepssion level depend on data source(text or images..)

Code:

	/**
	 * threshold value for compress
	 */
	public static final int THRESHOLD = 1200;

	/**
	 * Answer a byte array compressed in the DEFLATER format from bytes.
	 * 
	 * @param bytes
	 *            a byte array
	 * @return byte[] compressed bytes
	 * @throws IOException
	 */
	public static byte[] compress(byte[] bytes)
	{
		// Create the compressor with highest level of compression
		Deflater compressor = new Deflater();
		compressor.setLevel(Deflater.BEST_COMPRESSION);

		// Give the compressor the data to compress
		compressor.setInput(bytes);
		compressor.finish();

		// Create an expandable byte array to hold the compressed data.
		// You cannot use an array that's the same size as the orginal because
		// there is no guarantee that the compressed data will be smaller than
		// the uncompressed data.
		ByteArrayOutputStream bos = new ByteArrayOutputStream(bytes.length);

		// Compress the data
		byte[] buf = new byte[1024];
		while (!compressor.finished())
		{
			int count = compressor.deflate(buf);
			bos.write(buf, 0, count);
		}
		try
		{
			bos.close();
		}
		catch (IOException e)
		{
		}

		// Get the compressed data
		byte[] compressedData = bos.toByteArray();
		return compressedData;
	}

	/**

	 * 
	 * @param bytes
	 *            a byte array
	 * @return byte[] compressed bytes
	 * @throws IOException
	 */
	public static byte[] uncompress(byte[] bytes)
	{

		Inflater decompressor = new Inflater();

		{
			try
