Wouldn't a better pattern be the discovery pattern in the services docs :

import o.a.c.l.LogFactory;

public class MyFoo {

Log logger = null;

static {

  Iterator i = Service.providers(LogFactory.class);

       while (i.hasNext()) {            LogFactory lf = (LogFactory) i.next(); logger = lf.getLogger(....); }     }

public void foo() { logger.log("hi from foo"); } }

Question - could o.a.c.l.LogFactory be an interface in this case? I am guessing yes, but not sure...

So in this case, the pull discovery is maintained ("Not taken away...") yet implementation freedom is restored...
