Tomcat 9 doesn't have tomcat.pid file

I've installed Tomcat 9 on Ubuntu 18.04, and trying to add it to service.

However, unlike other users, tomcat.pid file doesn't exist anywhere. So my Tomcat service file generates an error.

[Unit]
Description=Apache Tomcat 9 Servlet Container
After=syslog.target network.target
[Service]
User=nblizz
Group=nblizz
Type=forking
Environment=CATALINA_PID=/opt/apache-tomcat-9.0.16/tomcat.pid <--- !! (Not exist)
Environment=CATALINA_HOME=/opt/apache-tomcat-9.0.16
Environment=CATALINA_BASE=/opt/apache-tomcat-9.0.16
ExecStart=/opt/apache-tomcat-9.0.16/bin/startup.sh
ExecStop=/opt/apache-tomcat-9.0.16/bin/shutdown.sh
Restart=on-failure
[Install]
WantedBy=multi-user.target

Running Tomcat is fine, but error message is displayed when stopping tomcat.

Plus, the color of apache-tomcat.service file is different from the others. ()

What is the problem?

It looks like there was a change from v9.0.14 in the catalina.sh file

$ diff bin/catalina.sh ../tomcats/apache-tomcat-9.0.14/bin/catalina.sh

< 2\>\&1 \&\& echo \$! \>\“$catalina_pid_file\” \; \} $catalina_out_command “&”

> 2\>\&1 \& echo \$! \>\“$catalina_pid_file\” \; \} $catalina_out_command “&”

< 2\>\&1 \&\& echo \$! \>\“$catalina_pid_file\” \; \} $catalina_out_command “&”

> 2\>\&1 \& echo \$! \>\“$catalina_pid_file\” \; \} $catalina_out_command “&”

If you remove the extra ampersand there, the pid file is created as expected.
