Hello,
I'm using Apache Tomcat/8.5.35, jvm 1.8.0_192-b12, Windows Server 2012
R2 and at Complete Server Status page I can see list of all http-nio
threads and I can see a header of ajp-nio threads. But there is
displayed only a label Max threads:
and nothing more.
In the localhost.log is an exception:
04-Dec-2018 10:31:38.109 SEVERE [96]

At the version Apache Tomcat/8.5.34 this problem doesn't occur.
Did I found a bug?
