I noticed that ObjectEncoderOutputStream uses ObjectOutputStream . 我注意到ObjectEncoderOutputStream使用ObjectOutputStream 。 Traditionally ObjectOutputStream can cause an OOME if it's not reset on a regular basis. 传统上，如果不定期重置ObjectOutputStream则会导致OOME。 Is ObjectEncoderOutputStream susceptible to this? ObjectEncoderOutputStream容易受到此影响吗？

No , the ObjectEncoderOutputStream is not susceptible to the same problem, because of the way it uses the ObjectOutputStream . 不，由于ObjectEncoderOutputStream使用ObjectOutputStream的方式，因此不易受到相同问题的影响。

For each writeObject call a new ObjectOutputStream (specifically a CompactObjectOutputStream ) is created to write that single object and then it is closed again. 对于每个writeObject调用，都会创建一个新的 ObjectOutputStream （特别是CompactObjectOutputStream ）来写入该单个对象，然后将其再次关闭。

Thus, no ObjectOutputStream ever holds on to old references and thus doesn't cause a OOM this way. 因此，任何ObjectOutputStream都不会保留旧的引用，因此不会以这种方式引起OOM。
