Hi, this is really serious issue if you want to build media application with Vaadin 7. Problem when you use
FileResource
+
Chrome
browser.
In my application I use Audio/Video component and FileResource. For example I have modal window with audio component. If I close window before audio fully loaded I get a problem. This stream hung and doesn’t close.
After opening and closing in this way, 8 audio files all thread in my container Server are locked and application fully hung. And only when I click F5 or refresh the page I get Exceptions from all media components:
SEVERE: Servlet.service() for servlet [com.example.productlist.ProductlistUI$Servlet]
in context with path
[/ProductList] threw exception [com.vaadin.server.ServiceException: ClientAbortException: java.net.SocketException: Software caused connection abort: socket write error]
with root cause
