Convert UUID to byte array and vice versa. Useful for when UUIDs are stored in MySQL tables as VARBINARY(16)

	import java.nio.ByteBuffer;
	import java.util.UUID;

	public class UuidAdapter {
	public static byte[] getBytesFromUUID(UUID uuid) {
	ByteBuffer bb = ByteBuffer.wrap(new byte[16]);
	bb.putLong(uuid.getMostSignificantBits());
	bb.putLong(uuid.getLeastSignificantBits());

	return bb.array();
