在使用Java8的Lambda表达式重写Collections.sort()方法时遇到错误：INVOKESPECIAL/STATIC on interfaces require ASM5。该问题在Spring框架环境下出现，通过直接使用Lambda表达式而非方法引用得以解决。

使用 Java8 Lambda 重写Collections.sort()时报错

packetPrizeItems.sort(Comparator.comparingInt(PacketPrizeItem::getWeight));

修改成下面就好了还不知道是为什么

Collections.sort(packetPrizeItems, (p1, p2) -> (p1.getWeight() - p2.getWeight()));
