aeron - 无法为 Aeron 媒体驱动程序设置 ThreadFactory()

Question

我无法在 Aeron 的 LowLatencyMediaDriver 示例中设置新的 Threadfactory()。有关 VisualVM 中线程名称的代码和快照，请参见下面的代码。

public class LowLatencyMediaDriver {
    public static void main(final String[] args) {
        loadPropertiesFiles(args);

        ThreadFactory conductorThreadFactory = new ThreadFactoryBuilder().setNameFormat(LowLatencyMediaDriver.class.getName()+"-Conductor-%d").setDaemon(true).build();
        ThreadFactory receiverThreadFactory = new ThreadFactoryBuilder().setNameFormat(LowLatencyMediaDriver.class.getName()+"-Receiver-%d").setDaemon(true).build();
        ThreadFactory senderThreadFactory = new ThreadFactoryBuilder().setNameFormat(LowLatencyMediaDriver.class.getName()+"-Sender-%d").setDaemon(true).build();

        final MediaDriver.Context ctx = new MediaDriver.Context()
            .termBufferSparseFile(false)
            .threadingMode(ThreadingMode.DEDICATED)
            .conductorThreadFactory(conductorThreadFactory)
            .receiverThreadFactory(receiverThreadFactory)
            .senderThreadFactory(senderThreadFactory)
            .conductorIdleStrategy(new BusySpinIdleStrategy())
            .receiverIdleStrategy(new BusySpinIdleStrategy())
            .senderIdleStrategy(new BusySpinIdleStrategy());

        try (MediaDriver ignored = MediaDriver.launch(ctx)) {
            new ShutdownSignalBarrier().await();
            System.out.println("Shutdown Driver...");
        }
    }
}

AgentRunner 类自动重命名线程并且不保留通过 ThreadFactory() 给出的名称。
