Hi all.
I have set up a server-side events mechanism using tomcat (and
https://github.com/byjg/jquery-sse), and everything is working smoothly.
But each time the server tries to send some data on an SSE channel which
has just been closed on the client side, even though this exception is
catched and handled in my SSE servlet, I see this exception in the
webapp log:

With a lot of users this can really pollute the logs. Is there any way
to silence this stacktrace?
I'm using Java 1.8.0_101 on linux 64 bits, and Tomcat 8.5.9.
Thanks,
Claude
