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

At the version Apache Tomcat/8.5.34 this problem doesn't
occur. Did I found a bug?
Something looks seriously broken if you got an NPE on that line of
code. Either the Valve doesn't have a Container or the Container
doesn't have a logger, neither of which should ever happen.
What's your use-case? Is this embedded, or using Tomcat "normally"
like starting-up from a script/service and deploying web
applications to it?
The tomcat is started as a Windows service tomcat7.exe. The
services was installed using service.bat install. User
connections are received in Apache Server and reverse proxied
using mod_ajp. The manager app I've opened locally at RDP at url
http://localhost:8080/manager/html.
Did you upgrade from 8.5.34 and then it broke? How did you perform
the upgrade?
I upgraded from 8.5.9 to 8.5.35 just copying from
apache-tomcat-8.5.35-windows-x64.zip. I didn't copy only the
conf/server.xml If I copied files from 8.5.34 the problem didn't
occur.
So you took files from the ZIP file and dropped them on top of your
existing Tomcat installation?
Yes.
Before that I've made a directory synchronization to view what files are
new, modified and same.
Which files? All of them?
And then I've copied all of them except server.xml where I have my
customizations.
Generally,
conf/server.xml is customized for a particular environment. If you
copied everything, you will probably have lost something important.
I do not understand how I can lost something important, if I've copied
everything.
There could be a jar hell when in the zip would be jar with newer
version numbers in name. But this is not this issue for upgrade from
8.5.9 to 8.5.39.
No new jar is in the zip.
I've also text compared source a my server.xml to inspect some new
sections in source server.xml and have nothing found.
