Robovm 无法通过 https 下载图像

Question

我正在尝试使用 httpurl 连接从 fb 下载头像图像。这适用于 android。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。如果我尝试在 iOS 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）。我应该为 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);

我运行此代码在 try/catch/finally 块中，代码跳到 connect() 之后的最后（我断开连接的地方）。它抛出 IllegalMonitorStateException。

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