oniStreamDestroy called by VideoStream.destroy() freezes thread

[Windowsfreak]

In SimpleViewer.java, switching from Depth to IR or from IR to Depth will cause the old videoStream to be destroyed. But calling the NativeMethod oniStreamDestroy freezes the thread. (Using OpenNI-Windows-x64-2.2.0.33-Beta)

void SimpleViewerApplication.selectedStreamChanged() {

    if (mVideoStream != null) {
        mVideoStream.stop();
        mViewer.setStream(null);
        mVideoStream.destroy(); // never returns
        mVideoStream = null;
    }

public void VideoStraem.destroy() {
    NativeMethods.oniStreamDestroy(this.getHandle(), this.mCallbackHandle); // never returns
    this.mStreamHandle = 0L;
}

Hi @Windowsfreak, I encountered the same issue while sequentially playing oni recorded files (and destroy the previous oni's). Did you find any solution/workaround?

I'm using dynamic library so I cannot spot where the problem is, but at least Xcode shows
