Is there a Java library that lets you "deserialize" a properties file directly into an object instance?

Example: say you have a file called init.properties:

username=fisk
password=frosk

and a Java class with some properties:

class Connection {

    private String username;
    private String password;

    public void setUsername(String username) {
        this.username = username;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

I want to do this:

Connection c = MagicConfigurator.configure("init.properties", new Connection())

and have MagicConfigurator apply all the values from the properties file to the Connection instance.

Is there a library with a class like this?
