Yes, that's weird, Maybe I think your test is not complete, you can change
x.y.z.B to a.b.c.B, and test it again to check whether the results are still
the same. I'm not sure about the behavior of the defineClass, but I think the
delegation loading only happen in `loadClass` method, in defineClass, it will
load with current loader. Maybe I'm wrong, but if we cannot explain my case,
then I'm not convinced that `alwaysParentFirstLoaderPatterns` will always make
class in the list loaded by parent loader unless it does not exist in the
parent classloader. .
