Unable to read and write Japanese folder structure in Tomcat 7, but it works for a Docker container

Question

Getting a FileNotFoundException while reading a Japanese folder structer from a Tomcat 7 web application. But it's working in a Docker container and direct java console execution.

Both Docker and normal tomcat7 setup and configurations are the same.

We have done following configurations:

1. Tomcat Server server.xml - In Connector tag added URIEncoding attribute as:

   <Connector port="8080"
              protocol="HTTP/1.1" 
              connectionTimeout="20000" 
              redirectPort="8443"
              URIEncoding="UTF-8"/>
   

2. catalina.sh - added following:

   export JAVA_OPTS="$JAVA_OPTS -server \
      -XX:-UseGCOverheadLimit \
      -Djava.awt.headless=true \
      -Djavax.servlet.request.encoding=UTF-8 \
      -Dfile.encoding=UTF-8"
   
   export CATALINA_OPTS="$CATALINA_OPTS \
      -Dfile.encoding='UTF-8'"`
   

3. Executed the following command to change the server language:

   export LC_ALL=en_US.UTF-8

Upgrade Tomcat7 to tomcat9 or Tomcat7.0.109. The support is not available in Tomcat7 Early versions
