What can you do is, simply use a System.exit() Method which terminates the current Java Virtual Machine running on the system. What does one do in this situation? Is there a way to exit at this very point? If these questions bother you, you have landed at the right place. While programming for one of these applications you may get stuck at some juncture of this program. I'm no Java expert so I probably shouldn't suggest any reasons for this unexpected behavior.Java is a wonderful programming language having numerous applications. Personally, I don't have any problems with Java apps in El Capitan. This may make your application disappear from the dock, but the app may still be running in the background.
QUIT ALL JAVA PROGRAMS UPDATE
Killall Dock only kills the Dock process, which forces an update of programs running. I would recommend fixing that weird exit bug of yours. If your process is no longer in ps's output, it's no longer running. This signal cannot be ignored by any process and is hence promptly terminated, no ifs or buts.Īs mentioned above, ps gives information of running processes. Kill -9 sends the undeniable SIGKILL signal to the process specified in PID. The format of ps's columns is PID/TTY/TIME/CMD. In this case, we used grep to filter out the specific process we were looking for. Ps gives information of running processes.
If the process is no longer there, you've successfully killed it. Now type, into terminal, substituting for your process' PID Substitute with the name of your process. You should be able to use Terminal to kill the process, if you know it's name with the following commands.įind the process identifier (PID).
QUIT ALL JAVA PROGRAMS HOW TO
I've seen various other topics where people had this issue with certain java programs under El Capitan, but most had very little detail, and none had a true fix to the issue.ĭoes anyone know why this happens? How to prevent it from happening in my programs? How to truly force quit applications like these? Shutting down normally is still impossible. This new application cannot be force quit through right-click, does NOT show up in the force quit window, and doesn't show up in Activity Monitor either. Furthermore, a terminal-looking window labeled "java" appears after running this command. BUT, the application still shows up in the force quit window, and it still cannot be force quit from there. I can run "killall Dock" from Terminal, which makes the application disappear from the dock. I have to force shutdown and reboot in order to get rid of this program. Shut-down is impossible while this application remains open. The application does not show up in Activity Monitor, so I can't end the process. If I open the force quit window with command-option-escape, the application shows up, but again, force quitting does nothing. I can right-click the icon and tell it to Force Quit, but this has no effect. I've been writing applications in eclipse, and one application of mine occasionally has an issue where the program ends, yet the java icon stays in the dock. I think there might be an issue on El Capitan with Java applications force quitting, because I've seen multiple people talk about similar problems to this with no actual solutions presented.
