This method iterates through the ClassLoaders returned by ClassLoaders.get() and tries to load the desired class.

Parameters:

name - the fully qualified name of the desired class.

initialize - whether the class must be initialized.

Returns:

the desired class.

Throws:

ClassNotFoundException - if the specified class could not be located by any loader returned by ClassLoaders.get()
