Description

When running on mustang, the arg tag does throws a ClassNotFoundException [1]. This is due to a change in the ClassLoader#loadClass() implementation [2]. The tag should be fixed to use the three-argument Class.forName method as specified in the bug description.

"ClassLoader.loadClass instance method, which does not (necessarily) support loading array classes, instead of using the static three-argument Class.forName method (like ObjectInputStream's own implementation of resolveClass uses). The Class.forName methods do support loading array classes using the same array class name syntax returned by Class.getName"
