Description
|
The JSR-201 Public Review Draft Spec says that it is illegal for a class to extend java.lang.Enum explicitly but compiler permits it. The following program should generate an compile-time error. In fact it crashes the compiler:
public class Junk extends Enum {
Junk() { super(null, 0); }
}

Work Around

|
Evaluation
|
This rule remains in the latest "preliminary proposed final draft 2"
(section III, second sentence) and so should be implemented in javac.
