How to reproduce the issue:
root@39d189491fd8:/usr/local/tomcat/webapps.dist/examples/WEB-INF/classes/nonblocking# java ByteCounter
Error: Could not find or load main class ByteCounter
Caused by: java.lang.NoClassDefFoundError: nonblocking/ByteCounter (wrong name: ByteCounter)

Your error is wrong name: ByteCounter because it's technically ByteCounter.java

# ls
'ByteCounter$1.class'                 ByteCounter.java                           NumberWriter.class
'ByteCounter$CounterListener.class'  'NumberWriter$1.class'                      NumberWriter.java
 ByteCounter.class                   'NumberWriter$NumberWriterListener.class'

I tested the webapp by moving the folder so it's accessible through the web https://github.com/docker-library/docs/tree/master/tomcat#how-to-use-this-image

Questions like these are better suited for a dedicated help resource, if you need further help I'd try asking over at the Docker Community Forums, Docker Community Slack, or Stack Overflow. Since these repos aren't really a user-help forum
