The Thread.print section of the jcmd man page can be updated to align with the update description.

If there is space, then we could include "and all mounted virtual threads".

(Note that there was a previous attempt to change this description when the Thread.print was updated to include mounted virtual threads. At the time, the PR feedback was to separate it to a different PR but there wasn't any follow-up on that so good to see it re-visited here)

}
static const char* impact() {
return "Medium: Depends on the number of threads.";
