Class loading in Jodd
There is one very cool tool in Jodd:
This method tries to load a class for given class name in the best way
possible, trying several different approaches. Here are more details.
First it tries to load a class using provided class loader (if it is provided, of course).
If this fails or if classloader is not provided, class will be loaded using current threads context class loader.
If this fails for some reason, Jodd will try to use callers class loader.
Jodd detects if all classloader are the same and will not repeat the loading if so. For example, if current threads context class loader is the same to callers class loader, it will not load class twice in case of failure.
Finally, if everything else fails, Jodd tries
ClassLoaderUtil#loadClass() is not special only because of
fail-safe approach for loading classes. It is also able to load
primitive classes, so
loadClass("int") would return
that's not all: it knows to load array classes as well! For
Class.forName is important here for loading array classes for
