Htop showing multiple java processes with different pids
htop, java, jvm, process
Solution
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.

Problem
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?
