Question

我正在编写一个适配器来在Apache Aries远程服务管理中使用chronicle队列。当我只使用一个线程时，它工作正常。有多个线程我得到如下的异常。

知道我做错了吗？

供参考，这是我的代码： https://github.com/cschneider/rsa-chronicle-provider/blob/master/src/test/java/org/apache/aries/rsa/provider/chronicle/ChronicleProviderTest.java

如果增加执行程序中的线程数，则可以看到异常。

看起来Chronicle appender不是线程安全的，因此必须同步写入同一队列。

请参阅FAQ: Can I have multiple writers?

写入具有多个线程的编年史队列 - ＆gt; java.nio.BufferOverflowException
