RoboVM 应用程序在 ptr.get() 上崩溃

Question

需要某种魔法才能让ptr.get()工作吗？由于某种原因，以下代码总是使我的应用程序崩溃：

    AudioStreamBasicDescription asbd = new AudioStreamBasicDescription(mSampleRate, mFormatID, mFormatFlags, mBytesPerPacket, mFramesPerPacket, mBytesPerFrame, mChannelsPerFrame, mBitsPerChannel, 0);
    AudioFilePtr outAudioFile = new AudioFilePtr();
    File f = File.createTempFile("ptt", ".caf"); 
    AudioFileError afe = AudioFile.createWithURL(new NSURL(f), 1667327590, asbd, 1, outAudioFile);
    System.out.println(afe.name());
    System.out.println(outAudioFile.get());

它成功地从AudioFile.createWithURL返回，没有错误（错误代码：否），但是一旦我尝试获取java实例就会崩溃。我在另一段代码中也遇到了相同类型的崩溃，我将 AudioQueuePtr 实例化为 queueptr，将其传递给AudioQueue.newInput并尝试调用queueptr.get()。我在这里缺少什么吗？

java中没有堆栈跟踪，但这里是XCode Organizer设备日志：

事实证明，

这是RoboVM绑定中的一个错误。应在将来的版本中修复。在此处查看错误报告：https://github.com/robovm/robovm/issues/627

另外，我在这里发布了一个完整的工作示例：使用AudioQueue录制演示的RoboVM实现导致"未找到@Marshaler"错误
