Override annotation and JDK 1.5

I'm using JDK 1.5, here is my class:

public final class Account implements ICAccount

{
//...
   @Override
   public ObjectID getId()
   {
      return new ObjectID(id);
   }
//...
}

Account overrides method getId() from ICAccount

But compilation fails. 

Account.java  method does not override a method from its superclass

If i'm using JDK 1.6 the compilation succeeds.

In documentation to @Override annotation I see 

Since:
1.5

What is the problem?

In Java 1.5 the @Override annotation is not allowed for methods that implement an interface method, only for methods that in fact override methods from a superclass. This changed in Java 1.6.

The Override annotation is only used when overriding methods from classes in java 1.5. It also works for implementation of interface methods from Java 1.6.
