Subject [jira] (MSHARED-295) Non reliable killing of processes by CommandLineUtils
Date Tue, 10 Sep 2013 07:31:52 GMT

Kristian Rosenvold commented on MSHARED-295:
--------------------------------------------

And selenium uses JNA on windows and also shells to kill on linux. Killing firefox cross platform
turns out to be one of the hardest problems in computer science. That stuff about P and NP
is just kids stuff compared.

> CommandLineUtils is used in Maven-Surefire to start forks which execute tests. It is
a well known issue that sometimes child processes are not killed correctly. This is a known
limitation of JVM, and the only reliable way to implement it would be platform specific.
> Bug report in Surefire JIRA:
> http://jira.codehaus.org/browse/SUREFIRE-773
> JVM bug report. It's Windows specific, but the problem exists on Linux and OSX as well.
> http://bugs.sun.com/view_bug.do?bug_id=4770092
> I'm proposing either 1) to implement several platform specific implementations of ProcessHook
or 2) to make the mechanism of killing processes extendable for clients of the library.
