Why are we getting ClosedByInterruptException from FileChannel.map in Java 1.6?
提问by bmargulies
A customer of ours complains that, sporadically, calls of ours to FileChannel.mapfail with a ClosedByInterruptException. The Javadocdoes not list this as a legitimate possibility. Does anyone know what might be going on here?
我们的一位客户抱怨说，我们的客户偶尔FileChannel.map会因为ClosedByInterruptException. 在Javadoc中没有列出这是一个合法的可能性。有谁知道这里会发生什么？

Channel operations are bound to the thread doing the operations. If this thread is interrupted, the stream / channel is closed due to IO safety issues.
通道操作绑定到执行操作的线程。如果此线程中断，则由于 IO 安全问题，流/通道将关闭。

The last comment contains the answer. There was a thread pool in use, and at shutdown interrupts were delivered.
最后一条评论包含答案。有一个线程池正在使用中，并在关闭时传递中断。
