Mixed modifiers
You cannot put @Abstract together with @Shared, @Open, or @Override in the same declaration.
Class extension
When a class without @Abstract inherits from an abstract class, the child class must supply implementations of all abstract methods and properties that it inherited.

You can declare abstract methods and properties only in an abstract class.
