JSONType#ignores not working on "isXxx" java bean properties

[captmjc]

com.alibaba.fastjson.annotation.JSONType#ignores does not work during serializing java beans to JSONs when there are some public boolean isXxx() methods. Test codes are listed below:

@JSONType(ignores = {"xxx", "yyy"})
public class Test {

    public boolean isXxx() {
        return true;
    }
    public boolean getYyy() {
        return true;
    }
    public boolean getZzz() {
        return true;
    }
    public static void main(String[] args) {
        Object json = JSON.toJSON(new Test());
        System.out.println("Expected: {\"zzz\":true}");
        System.out.println("  Actual: " + json);
    }
}
