Affects: \
Starting from version 5.2.10.RELEASE on HTTP response AbstractGenericHttpMessageConverter (Jackson) tries too flush already closed stream .
Seems Tomcat handles this gracefully, even if org.apache.catalina.connector.OutputBuffer.closed == true on the last flush.
But this causes problems for OpenLiberty: https://github.com/OpenLiberty/open-liberty/issues/14875
Here is repository with example for OL: https://github.com/pkunk/wlp-spring
