Description
SA jmap heap dumper uses different super classes for array classes. For eg. for String[].class, Object[].class is used as super class and so on. In "Java view", all array classes have java.lang.Object as super class. (for eg. refer to javadoc of java.lang.Class.getSuperclass method).

Comments
EVALUATION Use Klass.getJavaSuper() instead of Klass.getSuper() when dumping superclass ID. ArrayKlass.getJavaSuper() is overriden to return java.lang.Object class. Refer to "Suggested Fix" for changes.
