Hello, I'm using Apache Tomcat/8.5.35, jvm 1.8.0_192-b12, Windows

there is displayed only a label Max threads: and nothing more.

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.
