The syntax for obtaining array classes using Class.forName is
rather wacked, but it does work. For example, to get the
class for an Object[], use
Class oaClass = Class.forName("[Ljava.lang.Object;");
Both the "[L" prefix and trailing ";" are required.
The javadoc for the Class.getName method describe the syntax
required.
