It appears the port number 8005, where tomcat is listening for SHUTDOWN signal, is already used by another process. It's a little bit odd, since I just started Windows and ran Tomcat as the first command.

I suspected it was some windows service program that automatically started when windows is started. It turned out to be some apple software is running on port 8005. After I removed that apple software, I was able to run Tomcat using the default port number 8005. This site lists port numbers used by some apple software.

Alternatively, I could just change Tomcat to use another port number by editing %CATALINA_HOME%\conf\server.xml:

<Server port="8006" shutdown="SHUTDOWN">
