Coverity报错equals() 的实现有问题 (FB.EQ_UNUSUAL)

错误例子:

 普通类:

public boolean equals(Object object) {
          final EqualsStrategy2 strategy = JAXBEqualsStrategy.INSTANCE;
          return equals(null, null, object, strategy);
}

           应该判断是否为null和是否为Object,改成

public boolean equals(Object object) {
	if ((object == null)||(this.getClass()!= object.getClass())) {
	    return false;
	}

	return equals(null, null, object, JAXBEqualsStrategy.INSTANCE);
}

或者这样

public boolean equals(Object object) {
	if ((object == null)||(this.getClass()!= object.getClass())) {
	    return false;
	}
	if (this == object) {
		return true;
	}
	return equals(null, null, object, JAXBEqualsStrategy.INSTANCE);
}

Null.java(用来代替null)

        @Override
        public boolean equals(Object object) {
            return object == null || object == this;
        }

改成

        @Override
        public boolean equals(Object object) {
            if (null == object || getClass() == object.getClass()) {
                return true;
            }

            if (this == object) {
                return true;
            }

            return false;
        }
