java - Robovm 无法通过 https 下载图像

Question

我正在尝试使用 httpurlconnection 从 Facebook 下载头像图像。这在安卓上运行良好。如果我从非 SSL 服务器下载任意图像，它也可以在 iOS 上使用 robovm 运行。如果我尝试在 iOS 上下载 Facebook 头像，几乎每次都会失败。有时它确实有效(似乎是随机的)。我应该对 iOS 使用不同的方法吗？

我使用以下代码下载我的图像(在单独的线程中)

HttpURLConnection conn= (HttpURLConnection)url.openConnection(); 
conn.setDoInput(true); 
conn.connect(); 
int length = conn.getContentLength(); 
if(length<=0) return null; 
InputStream is = conn.getInputStream();
DataInputStream dis = new DataInputStream(is);
byte[] data = new byte[length]; 
dis.readFully(data); 
Pixmap pixmap = new Pixmap(data, 0, data.length);

我在 try/catch/finally block 中运行此代码，代码在 connect() 之后立即跳到finally(我断开连接的地方)。它抛出一个 IllegalMonitorStateException。

java.lang.IllegalMonitorStateException: unlock of unowned monitor

完全重新安装 roboVM 插件后，此问题已得到解决。我不知道真正的问题是什么。
