Given that the current double-checked locking code does not work, I've put together another version of the code, shown in Listing 7, to try to prevent the out-of-order write problem you just saw.
考虑到当前的双重检查锁定不起作用，我加入了另一个版本的代码，如清单7所示，从而防止您刚才看到的无序写入问题。
Instead of double-checked locking, use the Initialize-on-demand Holder Class idiom, which provides lazy initialization, is thread-safe, and is faster and less confusing than double-checked locking.
不使用双重检查锁定，而使用Initialize - on - demandHolderClassidiom，它提供了迟缓初始化，是线程安全的，而且比双重检查锁定更快且没那么混乱。
JSR-133 is addressing issues regarding the memory model, however, double-checked locking will not be supported by the new memory model. Therefore, you have two options.
