Mendix 7 upgrade all java actions error

Hi. After upgrading from 6 to 7 all my java Actions have the following errors. is this change correct?   1. getContext(), must be changed to  context() ??? 2. @Override in my toString which all my JavaActions had.  must be removed??? 3.  All the classed show error: The hierarchy of the type xxx is inconsistent   just a sample java action class with the errors.   public class VerifyPassword extends CustomJavaAction {    private java.lang.String userName;    private java.lang.String password;    public VerifyPassword(IContext context, java.lang.String userName, java.lang.String password)    {       super(context);       this.userName = userName;       this.password = password;    }    @Override    public java.lang.Boolean executeAction() throws Exception    {       // BEGIN USER CODE       IUser user = Core.getUser(getContext(), userName);       return user != null && Core.authenticate(getContext(), user, password);   seem i need to change to  IUser user = Core.getUser(context(), userName); return user != null && Core.authenticate(context(), user, password);         // END USER CODE    }    /**     * Returns a string representation of this action     */    @Override  ?? not happy with the override anymore    public java.lang.String toString()    {       return "VerifyPassword";    }    // BEGIN EXTRA CODE    // END EXTRA CODE }
