Hi, It'll be useful to have those details. I think we can just update the command to work in Java 8 for now. Connecting to the JVM to get these kinds of stats will have an impact on the server, but it should be okay as we run carbondump to debug the server.
I think we must go through all commands in the carbondump and make sure that all of those are still relevant for today. I can do that later. Thanks!
