BUG: ClassView Incorrectly Allows Non-Abstract/Abstract Method

• Microsoft Visual J++, versions 1.0, 1.1

SYMPTOMS

ClassView allows you to add methods that use the abstract modifier to non- abstract classes. In Visual J++ 1.0 it also allows you to add methods that do not use the abstract modifier to interfaces. As a result, errors occur when you compile the source code. ClassView should not allow these scenarios.

RESOLUTION

Avoid adding methods that use ClassView in this manner.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Steps to Reproduce Behavior

In Visual J++ 1.0, add the following interface definition to an AppWizard- generated Java applet:

   interface Test{}

   Save the changes to the file, and view the ClassView tab of the Project
   Workspace window. The "new" interface Test appears in the project
   "classes" display. In the ClassView pane, right-click "interface Test"
   to open the context menu. Use the context menu to add a non-abstract
   class method to the interface Test. Invalid Java code is generated that
   can cause various compile-time errors.

   class Test1{}

   Save the changes to the file, and view the ClassView tab of the Project
   Workspace window. The "new" class Test1 appears in the project "classes"
   display. In the ClassView pane, right-click "class Test1" to open the
   context menu. Use the context menu to add an abstract class method to
   the class Test1. Invalid Java code is generated that can cause various
   compile-time errors.
