Xcode 9 (Swift 4) - java.net.SocketTimeoutException

When I try to create a https POST Request i get a SocketTimeoutException when closing the OutputStream.

I use the latest j2objc version with the new Xcode 9 (iOS-App).

I attached an Example Project which also contains the Java "Request.java" Class.

Full Stack Trace:
