是从下面触发了finalize()方法发出，但是现在这个里面也已经没有做任何操作了，是不是可以把finalizerGuardian去掉了？
private final Object finalizerGuardian = new Object() {
@Override
protected void finalize() throws Throwable {
super.finalize();
if (!ReferenceConfig.this.destroyed) {
logger.warn("ReferenceConfig(" + url + ") is not DESTROYED when FINALIZE");
/* don't destroy for now
try {
ReferenceConfig.this.destroy();
} catch (Throwable t) {
logger.warn("Unexpected err when destroy invoker of ReferenceConfig(" + url + ") in finalize method!", t);
}
*/
}
}
};
