Hotswap Not Working

[mtwallach]

I've configured hotswapping per instructions but it does not appear to be working. It seems my Dockerfile & docker-compose changes are working properly but i do not see message noted in documentation that indicates success. Only mention in logs I see of extraClasspath is : Unable to set extraClasspath to [file:/usr/local/tomcat/hotswap-agent/] on classLoader

I had configuration issue, still not working but issue is no longer this. Maybe should be more specific on naming of volumes (Step 5 --- Hotswap Agent in Project (JDK11))
