Htop showing multiple java processes with different pids

Htop on my linux machine shows many "processes" after launching one java program/JVM. I do understand that the JVM runs multiple
threads (for the actual program, for garbage collection, etc).

But how come htop lists them as multiple processes with different pids. What exactly are those processes?

Actually, it's just that htop by default shows each thread as a separate process. You can add the line hide_userland_threads=1 to your ~/.config/htop/htoprc file to show only one line.
