Unable to write the complete message as the WebSocket connection has been closed

Question

We have Vaadin Push enabled with @Push(transport = Transport.WEBSOCKET_XHR). When UI detached, we see the below exception at the log.

Seems like it does not impact anything other than errors at the log. Do you know how to close the connection nicely so we do not fill the log with those errors?

Thank you in advance.

What do you mean by "UI detached"? When you close the browser window, the server side has no chance to know this and throws the message mentioned — André Schild, Mar 27 '16 at 09:58
No, not the browser window closing. it is when Vaadin UI is detached. For example when user logout. — turgos, Mar 27 '16 at 11:47
Here is the Vaadin Ticket I found, but there is not any solution/workaround mentioned: https://dev.vaadin.com/ticket/19376 — turgos, Mar 28 '16 at 13:38

Thank you for your reply Alexander. We use Spring Boot 1.3.3 and it uses Tomcat 8 by default. Maybe I am wrong, I will check again. We have the above exception when user logs off or other times when the current Vaadin UI is detached. That's why I feel like It is somehow related to Vaadin not closing the connection gently. As I said, I am not sure tough. – turgos Mar 30 '16 at 14:32
Yes, you are correct Alexander, It is a Tomcat bug indeed. – turgos Mar 31 '16 at 01:48

Alexander's answer is correct. You need to upgrade 8.0.33 to overcome this issue, and this is how I managed to change Tomcat version for Spring Boot and Gradle.

  compile("org.springframework.boot:spring-boot-starter-web") {
    exclude module: "spring-boot-starter-tomcat"
  }
  //Because of the websocket defect on tomcat, I comment out the below line 
  //providedRuntime("org.springframework.boot:spring-boot-starter-tomcat")
  compile 'org.apache.tomcat.embed:tomcat-embed-core:8.0.33'
  compile 'org.apache.tomcat.embed:tomcat-embed-el:8.0.33'
  compile 'org.apache.tomcat.embed:tomcat-embed-logging-juli:8.0.33'
  compile 'org.apache.tomcat.embed:tomcat-embed-websocket:8.0.33'

Using Maven you can simply set the property `8.0.33`. Not sure if something similar is possible using Gradle. — herman, Apr 01 '16 at 21:27
Apparently it is: see [docs](http://docs.spring.io/spring-boot/docs/1.3.3.RELEASE/reference/htmlsingle/#_use_tomcat_7_with_gradle). Basically, add `ext['tomcat.version'] = '8.0.33'` — herman, Apr 01 '16 at 21:35
