java.exe does not end when using GLGraphics

in Contributed Library Questions • 1 years ago

I made a program that uses GLgraphics and the problem is that when I close the program, java.exe doesn't close so I have to manually end the process every time. The window will close, but java.exe will still be running, meaning I can't run the sketch again until I close it. Does anybody know how to fix this?

Hi Shoffing!

Im bumping this post!

Im having this same issue, the java.exe process persists and continues using around 13% cpu. It only seems to happen when using the GLGraphics rendering. Did you ever find a solution for this?

I tried some of the stop() and exit() methods described here: https://forum.processing.org/topic/run-code-on-exit but no luck.

Thanks!

I had a similar issue when using shaders on Windows 7 machines with a ATI HD3470. Here is what I ended up doing:

OS = System.getProperty("os.name");
try {
if (OS.equalsIgnoreCase("Windows 7")
|| OS.equalsIgnoreCase("Windows Vista")) {
String pidstr = java.lang.management.ManagementFactory
.getRuntimeMXBean().getName();
String pid[] = pidstr.split("@");
Runtime.getRuntime().exec("taskkill /F /PID " + pid[0])
.waitFor();
}
} catch (Exception e) {
/**
* oh just die already... what is this thing, a zombie?
*/
}

Hi Jeff,

Thanks for the response!

Using your solution above in the exit() method, after the super call seems to help, but only when pressing 'esc' in the sketch. Pressing the stop button seems to skip the exit() alltogether. I guess Ill just have to remember that :)

Im glad there is a solution to this, I wonder if it is a larger bug of the IDE or of Processing itself.

Thanks again!
