Your understanding is correct.
In this case, you could intercept the request before you defer to the
System/Parent classloader. Are you saying that that _couldn't_ work?
No, it would really work, because you cannot force everyone to use your
class loader to load their classes. Certainly Felix can force bundles to
use its class loader, but that is about it.
For example, assume I write MyHost:
public class MyHost {
Felix felix = null;
public MyHost() {
URL.setURLStreamHandlerFactory(...);
felix = new Felix();
}
}
In such a situation, Felix has no control over the class loader loading
MyHost.class, so URL.class would be loaded by some other class loader
(most likely the standard app class loader).
But if that MyHost code is running within a bundle, surely it would use
Felix's classloader?
What scenarios are there under which an app running in an OSGi container
would _not_ use the Felix classloader? That is, without the Felix
Classlaoder being somewhere in the classloader chain?
