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

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.

Answer 1

This is a Tomcat bug see https://bz.apache.org/bugzilla/show_bug.cgi?id=59014
please Upgrade to Tomcat version 8.0.33 or 7.0.69

Answer 2

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'
