/**
* Returns a representation of the named class. If the class is
* not under the same root as this JElement root, a representation
* of it will be synthesized via reflection (see note in class
* comments). The 'named' parameter must be a fully-qualified class
* name in the classfile 'Field Descriptor' format, a simple
* primitive name (e.g. 'long' or 'int'), or 'void'.
*
* A note regarding fully-qualified class names: if you're
* looking up a non-array type by name, you can just pass the
* regular, fully-qualified name. If you're looking up an array
* type, you need to use the 'Field Descriptor' format as described
* in secion 4.3.2 of the VM spec. This is the same name format
* that is returned by JClass.getFieldDescriptor.
*
* Inner classes cannot be loaded with this method. To load an inner
* class, you must load the outer class first and then call getClasses().
*
*
* Note that this method always returns some JClass - it never
* returns null or throws ClassNotFoundException. If neither a
* sourcefile not a classfile could be located for the named class,
* a stubbed-out JClass will be returned with the isUnresolved()
* flag set to true. This JClass will have a name (as determined by
* the given descriptor), but no other information about it will be
* available.
*
* @throws IllegalArgumentException if the parameter is null or not
* a valid class name.
