I want to suggest that these commands are not for everybody. But people investigating bugs in detail, including JVM crashes, might find these appealing, and should find the jcmd interface convenient. (It is convenient for the user, and also convenient to implement.) Proposing not having them in the standard jcmd help: I don't think most users should be attaching debuggers to their production JVMs, and I don't think most users should be doing these debug operations via jcmd on the same JVM. But we have a variety of expert users who want certain information. But I do think we should find other ways of documenting this, which might include our existing Troubleshooting Guide, but might well be something else. ------------- PR Comment: https://git.openjdk.org/jdk/pull/17655#issuecomment-1926559303
