Getting some unexpected issues when analysis my GW

Question

I have been developing an application using GWT and did a SonarQube implementation of it. But it did throw some unexpected results :

    bDateStart.addClickHandler(new ClickHandler(){
        @Override
        public void onClick(ClickEvent event) {

        }});

Major Issue : "Rename this class"

• Can Someone help me with above mentioned one ?
• And is there a way to turn 'off' certain rules for my application ?
• Is this really a major issue as shown by SonarQube ?
