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.



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.

In either Visual J++ 1.0 or 1.1, add the following class definition to an AppWizard-generated Java applet:   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.
