Macos io.netty.channel.nio.AbstractNioChannel.doBeginRead中的NullPointerException

我正在OSx上使用Play 2.5.0-M1

它工作正常，但在负载测试时会抛出一个错误：

这不是netty在mac上同时连接“50”的问题，因为即使是10个连接，它也会抛出错误。负荷试验为：

ab -n 500 -c 10 http://localhost:9000/

是否有人在以前版本的play中看到此错误

您有没有建议为什么会抛出此错误以及如何修复它

“它很好用”是什么意思？与测试运行相比，您的正常运行有什么不同？您是否使用不同的配置？到目前为止，我在进行负载测试时从未出现过这种异常。“它运行良好”意味着没有错误。我使用相同的配置。
