Hang when trying to get InputStream from url

[wkit23]

I'm facing a very odd case. Referring to the following code:

var url = java.import('java.net.URL');
var input = new url('http://localhost:3000/api/Quote/5490e46e500eb13c1e4ea0d1');
var con = input.openConnectionSync();
con.setConnectTimeout(10000);
con.setReadTimeout(10000);
var stream = con.getInputStreamSync();

Based on the code, there should not have issue right? However, the function always timed out (and hang if I didn't set the timeout). I can confirm that the url has no problem as I can open the page. I've even tried create the program in java and confirm no issue.

Any ideas? There isn't any error but it just doesn't give me the InputStream as I would needed.

Try adding sync to the end of setConnectTimeout and setReadTimeout

Nope. The problem is not at there. Calling directly url.openStream will cause it hang.

Make sure you understand the way node-java handles sync and async methods. url.openStream is an async call, so you have to pass a callback for it to work as expected. Alternatively, you can use url.openStreamSync().

Sorry, my mistake. I mean url.openStreamSync.
I finally found my mistake. Seems like I'm dealing with the thread issue where the stream is waiting to be open while the rest api waiting for the thread to continue. Hmm.. changing everything to async seems to kind fix the issue.

Thanks for your help Joe.
