Java db4o客户端/服务器同步中的复制错误

我在7.12和8.0中出现了一个奇怪的错误。我试图双向复制一个对象。它们都是db4o数据库，客户端通过嵌入式连接到本地数据库，并连接到db4o服务器以开始复制

系统为Mac OS X 10.7.3，Java-版本：

java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b04-415-11M3635)
Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01-415, mixed mode)

服务器上的错误是：

objc[7665]: Object 0x7ff03c0020e0 of class __NSArrayM autoreleased with no pool in place
- just leaking - break on objc_autoreleaseNoPool() to debug

客户端上的错误是：

java.lang.NullPointerException

我已经试着让它工作了几天了，但还没走多远

这个异常似乎与数组有关，但是，我在对象中没有使用类似数组的任何东西。但是，这可能是一个内部db4o结构

无论如何，感谢大家的帮助

---

干杯

嗯，我在第二个堆栈跟踪中没有看到任何复制堆栈帧，只有一个本机查询

消息“objc[7665]：对象0x7ff03c0020e0（类为_NSArrayM）在没有池的情况下自动删除 -只是泄漏-在objc_autoreleasenool（）上中断以进行调试”

我看起来很可疑。像db4o一样，它试图用MacOS内部的东西存储或序列化UI对象。我怀疑常规Java对象是否使用任何数组和引用计数

因此，我猜测您正在对服务器运行本机查询。无法将该查询转换为。在这种情况下，db4o尝试序列化查询对象并将其发送到服务器。该查询可能是一个内部类，并引用它的外部上下文，其中包含GUI对象。这就导致了这个问题

---

我的建议是：对服务器的查询只使用SODA查询。在客户机-服务器模式下，本机查询必须解决许多问题。将查询更改为导致此问题的SODA查询，然后查看它是否解决了此问题。

谢谢！这可能是一个问题，因为我确实希望基于属性值进行复制。此外，当问题发生时，我的服务器数据库中列出了一大堆类，包括GUI类，这可以用您所提到的来解释。我来看看。谢谢
