How do i use ThreadLocal to make my variable Safe in a Multi-Threaded Environment?

Suppose you have a Configuration object that needs to be stored.

    ........
    private static ThreadLocal myConfig = new ThreadLocal();
    ........
    public static void setThreadConfig(Configuration config)
    {
        myConfig.set(config);
    }

    public static void getThreadDefaultConfig()
    {
        return (Configuration)myConfig.get();
    }
